Gud Boi a72deef709 Refine `subint_forkserver` orphan-SIGINT diagnosis
Empirical follow-up to the xfail'd orphan-SIGINT test:
the hang is **not** "trio can't install a handler on a
non-main thread" (the original hypothesis from the
`child_sigint` scaffold commit). On py3.14:

- `threading.current_thread() is threading.main_thread()`
  IS True post-fork — CPython re-designates the
  fork-inheriting thread as "main" correctly
- trio's `KIManager` SIGINT handler IS installed in the
  subactor (`signal.getsignal(SIGINT)` confirms)
- the kernel DOES deliver SIGINT to the thread

But `faulthandler` dumps show the subactor wedged in
`trio/_core/_io_epoll.py::get_events` — trio's
wakeup-fd mechanism (which turns SIGINT into an epoll-wake)
isn't firing. So the `except KeyboardInterrupt` at
`tractor/spawn/_entry.py::_trio_main:164` — the runtime's
intentional "KBI-as-OS-cancel" path — never fires.

Deats,
- new `ai/conc-anal/subint_forkserver_orphan_sigint_hang_issue.md`
  (+385 LOC): full writeup — TL;DR, symptom reproducer,
  the "intentional cancel path" the bug defeats,
  diagnostic evidence (`faulthandler` output +
  `getsignal` probe), ruled-out hypotheses
  (non-main-thread issue, wakeup-fd inheritance,
  KBI-as-trio-check-exception), and fix directions
- `test_orphaned_subactor_sigint_cleanup_DRAFT` xfail
  `reason` + test docstring rewritten to match the
  refined understanding — old wording blamed the
  non-main-thread path, new wording points at the
  `epoll_wait` wedge + cross-refs the new conc-anal doc
- `_subint_forkserver` module docstring's
  `child_sigint='trio'` bullet updated: now notes trio's
  handler is already correctly installed, so the flag may
  end up a no-op / doc-only mode once the real root cause
  is fixed

Closing the gap aligns with existing design intent (make
the already-designed "KBI-as-OS-cancel" behavior actually
fire), not a new feature.

Gud Boi 76605d5609 Add DRAFT `subint_forkserver` orphan-SIGINT test
Tier-4 test `test_orphaned_subactor_sigint_cleanup_DRAFT`
documents an empirical SIGINT-delivery gap in the
`subint_forkserver` backend: when the parent dies via
`SIGKILL` (no IPC `Portal.cancel_actor()` possible) and
`SIGINT` is sent to the orphan child, the child DOES NOT
unwind — CPython's default `KeyboardInterrupt` is delivered
to `threading.main_thread()`, whose tstate is dead in the
post-fork child bc fork inherited the worker thread, not
main. Trio running on the fork-inherited worker thread
therefore never observes the signal. Marked
`xfail(strict=True)` so the mark flips to XPASS→fail once
the backend grows explicit SIGINT plumbing.

Deats,
- harness runs the failure-mode sequence out-of-process:
  1. harness subprocess runs a fresh Python script
     that calls `try_set_start_method('subint_forkserver')`
     then opens a root actor + one `sleep_forever` subactor
  2. parse `PARENT_READY=<pid>` + `CHILD_PID=<pid>` markers
     off harness `stdout` to confirm IPC handshake
     completed
  3. `SIGKILL` the parent, `proc.wait()` to reap the
     zombie (otherwise `os.kill(pid, 0)` keeps reporting
     it alive)
  4. assert the child survived the parent-reap (i.e. was
     actually orphaned, not reaped too) before moving on
  5. `SIGINT` the orphan child, poll `os.kill(child_pid, 0)`
     every 100ms for up to 10s
- supporting helpers: `_read_marker()` with per-proc
  bytes-buffer to carry partial lines across calls,
  `_process_alive()` liveness probe via `kill(pid, 0)`
- Linux-only via `platform.system() != 'Linux'` skip —
  orphan-reparenting semantics don't generalize to
  other platforms
- port offset (`reg_addr[1] + 17`) so the harness listener
  doesn't race concurrently-running backend tests
- best-effort `finally:` cleanup: `SIGKILL` any still-alive
  pids + `proc.kill()` + bounded `proc.wait()` to avoid
  leaking orphans across the session

Also, tier-4 header comment documents the cross-backend
generalization path: applicable to any multi-process
backend (`trio`, `mp_spawn`, `mp_forkserver`,
`subint_forkserver`), NOT to plain `subint` (in-process
subints have no orphan OS-child). Move path: lift
harness into `tests/_orphan_harness.py`, parametrize on
session `_spawn_method`, add
`skipif _spawn_method == 'subint'`.

Gud Boi 26914fde75 Wire `subint_forkserver` as first-class backend
Promote `_subint_forkserver` from primitives-only into a
registered spawn backend: `'subint_forkserver'` is now a
`SpawnMethodKey` literal, dispatched via `_methods` to
the new `subint_forkserver_proc()` target, feature-gated
under the existing `subint`-family py3.14+ case, and
selectable via `--spawn-backend=subint_forkserver`.

Deats,
- new `subint_forkserver_proc()` spawn target in
  `_subint_forkserver`:
  - mirrors `trio_proc()`'s supervision model — real OS
    subprocess so `Portal.cancel_actor()` + `soft_kill()`
    on graceful teardown, `os.kill(SIGKILL)` on hard-reap
    (no `_interpreters.destroy()` race to fuss over bc the
    child lives in its own process)
  - only real diff from `trio_proc` is the spawn mechanism:
    fork from a main-interp worker thread via
    `fork_from_worker_thread()` (off-loaded to trio's
    thread pool) instead of `trio.lowlevel.open_process()`
  - child-side `_child_target` closure runs
    `tractor._child._actor_child_main()` with
    `spawn_method='trio'` — the child is a regular trio
    actor, "subint_forkserver" names how the parent
    spawned, not what the child runs
- new `_ForkedProc` class — thin `trio.Process`-compatible
  shim around a raw OS pid: `.poll()` via
  `waitpid(WNOHANG)`, async `.wait()` off-loaded to a trio
  cache thread, `.kill()` via `SIGKILL`, `.returncode`
  cached for repeat calls. `.stdin`/`.stdout`/`.stderr`
  are `None` (fork-w/o-exec inherits parent FDs; we don't
  marshal them) which matches `soft_kill()`'s `is not None`
  guards

Also, new backend-tier test
`test_subint_forkserver_spawn_basic` drives the registered
backend end-to-end via `open_root_actor` + `open_nursery` +
`run_in_actor` w/ a trivial portal-RPC round-trip. Uses a
`forkserver_spawn_method` fixture to flip
`_spawn_method`/`_ctx` for the test's duration + restore on
teardown (so other session-level tests don't observe the
global flip). Test module docstring reworked to describe
the three tiers now covered: (1) primitive-level, (2)
parent-trio-driven primitives, (3) full registered backend.

Status: still-open work (tracked on `tractor#379`) doc'd
inline in the module docstring — no cancel/hard-kill stress
coverage yet, child-side subint-hosted root runtime still
future (gated on `msgspec#563`), thread-hygiene audit
pending the same unblock.

Gud Boi 25e400d526 Add trio-parent tests for `_subint_forkserver`
New pytest module `tests/spawn/test_subint_forkserver.py`
drives the forkserver primitives from inside a real
`trio.run()` in the parent — the runtime shape tractor will
actually use when we wire up a `subint_forkserver` spawn
backend proper. Complements the standalone no-trio-in-parent
`ai/conc-anal/subint_fork_from_main_thread_smoketest.py`.

Deats,
- new test pkg `tests/spawn/` (+ empty `__init__.py`)
- two tests, both `@pytest.mark.timeout(30, method='thread')`
  for the GIL-hostage safety reason doc'd in
  `ai/conc-anal/subint_sigint_starvation_issue.md`:
  - `test_fork_from_worker_thread_via_trio` — parent-side
    plumbing baseline. `trio.run()` off-loads forkserver
    prims via `trio.to_thread.run_sync()` + asserts the
    child reaps cleanly
  - `test_fork_and_run_trio_in_child` — end-to-end: forked
    child calls `run_subint_in_worker_thread()` with a
    bootstrap str that does `trio.run()` in a fresh subint
- both tests wrap the inner `trio.run()` in a
  `dump_on_hang()` for post-mortem if the outer
  `pytest-timeout` fires
- intentionally NOT using `--spawn-backend` — the tests
  drive the primitives directly rather than going through
  tractor's spawn-method registry (which the forkserver
  isn't plugged into yet)

Also, rename `run_trio_in_subint()` →
`run_subint_in_worker_thread()` for naming consistency with
the sibling `fork_from_worker_thread()`. The action is really
"host a subint on a worker thread", not specifically "run
trio" — trio just happens to be the typical payload.
Propagate the rename to the smoketest.

Further, add a "TODO — cleanup gated on msgspec PEP 684
support" section to the `_subint_forkserver` module
docstring: flags the dedicated-`threading.Thread` design as
potentially-revisable once isolated-mode subints are viable
in tractor. Cross-refs `msgspec#563` + `tractor#379` and
points at an audit-plan conc-anal doc we'll add next.

Gud Boi 4b2a0886c3 Mark `subint`-hanging tests with `skipon_spawn_backend`
Adopt the `@pytest.mark.skipon_spawn_backend('subint',
reason=...)` marker (a617b521) across the suites
reproducing the `subint` GIL-contention / starvation
hang classes doc'd in `ai/conc-anal/subint_*_issue.md`.

Deats,
- Module-level `pytestmark` on full-file-hanging suites:
  - `tests/test_cancellation.py`
  - `tests/test_inter_peer_cancellation.py`
  - `tests/test_pubsub.py`
  - `tests/test_shm.py`
- Per-test decorator where only one test in the file
  hangs:
  - `tests/discovery/test_registrar.py
    ::test_stale_entry_is_deleted` — replaces the
    inline `if start_method == 'subint': pytest.skip`
    branch with a declarative skip.
  - `tests/test_subint_cancellation.py
    ::test_subint_non_checkpointing_child`.
- A few per-test decorators are left commented-in-
  place as breadcrumbs for later finer-grained unskips.

Also, some nearby tidying in the affected files:
- Annotate loose fixture / test params
  (`pytest.FixtureRequest`, `str`, `tuple`, `bool`) in
  `tests/conftest.py`, `tests/devx/conftest.py`, and
  `tests/test_cancellation.py`.
- Normalize `"""..."""` → `'''...'''` docstrings per
  repo convention on a few touched tests.
- Add `timeout=6` / `timeout=10` to
  `@tractor_test(...)` on `test_cancel_infinite_streamer`
  and `test_some_cancels_all`.
- Drop redundant `spawn_backend` param from
  `test_cancel_via_SIGINT`; use `start_method` in the
  `'mp' in ...` check instead.

Gud Boi 189f4e3ffc Wall-cap `subint` audit tests via `pytest-timeout`
Add a hard process-level wall-clock bound on the two
known-hanging subint-backend tests so an unattended
suite run can't wedge indefinitely in either of the
hang classes doc'd in `ai/conc-anal/`.

Deats,
- New `testing` dep: `pytest-timeout>=2.3`.
- `test_stale_entry_is_deleted`:
  `@pytest.mark.timeout(3, method='thread')`. The
  `method='thread'` choice is deliberate —
  `method='signal'` routes via `SIGALRM` which is
  starved by the same GIL-hostage path that drops
  `SIGINT` (see `subint_sigint_starvation_issue.md`),
  so it'd never actually fire in the starvation case.
- `test_subint_non_checkpointing_child`: same
  decorator, same reasoning (defense-in-depth over
  the inner `trio.fail_after(15)`).

At timeout, `pytest-timeout` hard-kills the pytest
process itself — that's the intended behavior here;
the alternative is the suite never returning.

Gud Boi 4a3254583b Doc `subint` backend hang classes + arm `dump_on_hang`
Classify and write up the two distinct hang modes hit during Phase
B subint bringup (issue #379) so future triage doesn't re-derive them
from scratch.

Deats, two new `ai/conc-anal/` docs,
- `subint_sigint_starvation_issue.md`: abandoned legacy-subint thread
  + shared GIL → main trio loop starves → signal-wakeup-fd pipe fills
  → `SIGINT` silently dropped (`strace` shows `write() = EAGAIN` on the
  wakeup-fd). Un- Ctrl-C-able. Structurally a CPython limit; blocked on
  `msgspec` PEP 684 (jcrist/msgspec#563)

- `subint_cancel_delivery_hang_issue.md`: parent-side trio task parks on
  an orphaned IPC channel after subint teardown — no clean EOF delivered
  to the waiting receive. Ctrl-C-able (main loop iterates fine); OUR bug
  to fix. Candidate fix: explicit parent-side channel abort in
  `subint_proc`'s hard-kill teardown

Cross-link the docs from their test reproducers,
- `test_stale_entry_is_deleted` (→ starvation class): wrap
  `trio.run(main)` in `dump_on_hang(seconds=20)` so a future regression
  captures a stack dump. Kept un- skipped so the dump file is
  inspectable

- `test_subint_non_checkpointing_child` (→ delivery class): extend
  docstring with a "KNOWN ISSUE" block pointing at the analysis

Gud Boi 2ed5e6a6e8 Add `subint` cancellation + hard-kill test audit
Lock in the escape-hatch machinery added to `tractor.spawn._subint`
during the Phase B.2/B.3 bringup (issue #379) so future stdlib
regressions or our own refactors don't silently re-introduce the
mid-suite hangs.

Deats,
- `test_subint_happy_teardown`: baseline — spawn a subactor, one portal
  RPC, clean teardown. If this breaks, something's wrong unrelated to
  the hard-kill shields.
- `test_subint_non_checkpointing_child`: cancel a subactor stuck in
  a non-checkpointing Python loop (`threading.Event.wait()` releases the
  GIL but never inserts a trio checkpoint). Validates the bounded-shield
  + daemon-driver-thread combo abandons the thread after
    `_HARD_KILL_TIMEOUT`.

Every test is wrapped in `trio.fail_after()` for a deterministic
per-test wall-clock ceiling (an unbounded audit would defeat itself) and
arms `tractor.devx.dump_on_hang()` so a hang captures a stack dump
— pytest's stderr capture swallows `faulthandler` output by default.

Gated via `pytest.importorskip('concurrent.interpreters')` and
a module-level skip when `--spawn-backend` isn't `'subint'`.

Gud Boi d2ea8aa2de Handle py3.14+ incompats as test skips
Since we're devving subints we require the 3.14+ stdlib API
and a couple compiled libs don't support it yet, namely:
- `cffi`, which we're only using for the `.ipc._linux` eventfd
  stuff (now factored into `hotbaud` anyway).
- `greenback`, which requires `greenlet` which doesn't seem to be
  wheeled yet
  * on nixos the sdist build was failing due to lack of `g++` which
    i don't care to figure out rn since we don't need `.devx` stuff
    immediately for this subints prototype.
  * [ ] we still need to adjust any dependent suites to skip.

Adjust `test_ringbuf` to skip on import failure.

Also project wide,
- pin us to py 3.13+ in prep for last-2-minor-version policy.
- drop `msgspec>=0.20.0`, the first release with py3.14 support.

Gud Boi e90241baaa Add `parse_endpoints()` to `_multiaddr`
Provide a service-table parsing API for downstream projects (like
`piker`) to declare per-actor transport bind addresses as a config map
of actor-name -> multiaddr strings (e.g. from a TOML `[network]`
section).

Deats,
- `EndpointsTable` type alias: input `dict[str, list[str|tuple]]`.
- `ParsedEndpoints` type alias: output `dict[str, list[Address]]`.
- `parse_endpoints()` iterates the table and delegates each entry to the
  existing `tractor.discovery._discovery.wrap_address()` helper, which
  handles maddr strings, raw `(host, port)` tuples, and pre-wrapped
  `Address` objs.
- UDS maddrs use the multiaddr spec name `/unix/...` (not tractor's
  internal `/uds/` proto_key)

Also add new tests,
- 7 new pure unit tests (no trio runtime): TCP-only, mixed tpts,
  unwrapped tuples, mixed str+tuple, unsupported proto (`/udp/`),
  empty table, empty actor list
- all 22 multiaddr tests pass rn.

Gud Boi f84ef44992 Repair lifetime-stack suite's flakiness
Event on linux i was noticing lotsa false negatives based on sub
teardown race conditions, so this tries to both make way for
(eventually?) expanding the set of suite cases and ensure the current
ones are more reliable on every run.

The main change is to hange the `error_in_child=False` case to use
parent-side-cancellation via a new `trio.move_on_after(timeout)` instead
of `actor.cancel_soon()` (which is now toggled by a new `self_cancel:
bool` but unused rn), and add better teardown assertions.

Low level deats,
- add `rent_cancel`/`self_cancel` params to
  `crash_and_clean_tmpdir()` for different cancel paths;
  default to `rent_cancel=True` which just sleeps forever
  letting the parent's timeout do the work.
- use `trio.move_on_after()` with longer timeouts per
  case: 1.6s for error, 1s for cancel.
- use the `.move_on_after()` cancel-scope to assert `.cancel_called`
  pnly when `error_in_child=False`, indicating we
  parent-graceful-cancelled the sub.
- add `loglevel` fixture, pass to `open_nursery()`.
- log caught `RemoteActorError` via console logger.
- add `ids=` to parametrize for readable test names.

Gud Boi 1e0c57c6c5 Wrap cluster test in `trio.fail_after()`
Add a 6s timeout guard around `test_streaming_to_actor_cluster()`
to catch hangs, and nest the `async with` block inside it.
Found this when running `pytest tests/ --tpt-proto uds`.

Gud Boi b3ce5ab4f6 Swap `open_channel_from()` to yield `(chan, first)`
Deliver `(LinkedTaskChannel, Any)` instead of the prior `(first, chan)`
order from `open_channel_from()` to match the type annotation and be
consistent with `trio.open_*_channel()` style where the channel obj
comes first.

- flip `yield first, chan` -> `yield chan, first`
- update type annotation + docstring to match
- swap all unpack sites in tests and examples

Gud Boi 417b796169 Use `chan: LinkedTaskChannel` API in all aio-task fns
Convert every remaining `to_trio`/`from_trio` fn-sig style
to the new unified `chan: LinkedTaskChannel` iface added in
prior commit (c46e9ee8).

Deats,
- `to_trio.send_nowait(val)` (1st call) -> `chan.started_nowait(val)`
- `to_trio.send_nowait(val)` (subsequent) -> `chan.send_nowait(val)`
- `await from_trio.get()` -> `await chan.get()`

Converted fns,
- `sleep_and_err()`, `push_from_aio_task()` in
  `tests/test_infected_asyncio.py`
- `sync_and_err()` in `tests/test_root_infect_asyncio.py`
- `aio_streamer()` in
  `tests/test_child_manages_service_nursery.py`
- `aio_echo_server()` in
  `examples/infected_asyncio_echo_server.py`
- `bp_then_error()` in `examples/debugging/asyncio_bp.py`

Also,
- drop stale comments referencing old param names.

Tyler Goodlet 1f2fad22ee Extend `.to_asyncio.LinkedTaskChannel` for aio side
With methods to comms similar to those that exist for the `trio` side,
- `.get()` which proxies verbatim to the `._to_aio: asyncio.Queue`,
- `.send_nowait()` which thin-wraps to `._to_trio: trio.MemorySendChannel`.

Obviously the more correct design is to break up the channel type into
a pair of handle types, one for each "side's" task in each event-loop,
that's hopefully coming shortly in a follow up patch B)

Also,
- fill in some missing doc strings, tweak some explanation comments and
  update todos.
- adjust the `test_aio_errors_and_channel_propagates_and_closes()` suite
  to use the new `chan` fn-sig-API with `.open_channel_from()` including
  the new methods for msg comms; ensures everything added here works e2e.

Reorganize existing msg-related test suites under
a new `tests/msg/` subdir (matching `tests/devx/`
and `tests/ipc/` convention) and add unit tests for
the `_`-prefixed field filtering in `pformat()`.

Deats,
- `git mv` `test_ext_types_msgspec` and `test_pldrx_limiting` into
  `tests/msg/`.
- add `__init__.py` + `conftest.py` for the new test sub-pkg.
- add new `test_pretty_struct.py` suite with 8 unit tests:
  - parametrized field visibility (public shown, `_`-private hidden,
    mixed)
  - direct `iter_struct_ppfmt_lines()` assertion
  - nested struct recursion filtering
  - empty struct edge case
  - real `MsgDec` via `mk_dec()` hiding `_dec`
  - `repr()` integration via `Struct.__repr__()`

Gud Boi 5b2905b702 Xplatform tweaks for `daemon` fixture
There's a very sloppy registrar-actor-bootup syncing approach used in
this fixture (basically just guessing how long to sleep to wait for it
to init and bind the registry socket) using a `global _PROC_SPAWN_WAIT`
that needs to be made more reliable. But, for now i'm just playing along
with what's there to try and make less CI runs flaky by,

- sleeping *another* 1s when run from non-linux CI.
- reporting stdout (if any) alongside stderr on teardown.
- not strictly requiring a `proc.returncode == -2` indicating successful
  graceful cancellation via SIGINT; instead we now error-log and only
  raise the RTE on `< 0` exit code.
  * though i can't think of why this would happen other then an
    underlying crash which should propagate.. but i don't think any test
    suite does this intentionally rn?
  * though i don't think it should ever happen, having a CI run
    "error"-fail bc of this isn't all that illuminating, if there is
    some weird `.returncode == 0` termination case it's likely not
    a failure?

For later, see the new todo list; we should sync to some kind of "ping"
polling of the tpt address if possible which is already easy enough for
TCP reusing an internal closure from `._root.open_root_actor()`.

Namely, after trying to get `test_multi_daemon_subactors` to work for

the `test_ctxep_pauses_n_maybe_ipc_breaks` pattern matching for

`pytest`'s tmp dir generation, mega lulz.

Gud Boi 7b89204afd Tweak `do_ctlc()`'s `delay` default
To be a null default and set to `0.1` when not passed by the caller so
as to avoid having to pass `0.1` if you wanted the
param-defined-default.

Also,
- in the `spawn()` fixtures's `unset_colors()` closure, add in a masked
  `os.environ['NO_COLOR'] = '1'` since i found it while trying to debug
  debugger tests.
- always return the `child.before` content from `assert_before()`
  helper; again it comes in handy when debugging console matching tests.

Improve the `spawn` fixture teardown logic in
`tests/devx/conftest.py` fixing the while-else bug, and fix
`test_advanced_faults` genexp for `TransportClosed` exc type
checking.

Deats,
- replace broken `while-else` pattern with direct
  `if ptyproc.isalive()` check after the SIGINT loop.
- fix undefined `spawned` ref -> `ptyproc.isalive()` in
  while condition.
- improve walrus expr formatting in timeout check (multiline
  style).

Also fix `test_ipc_channel_break_during_stream()` assertion,
- wrap genexp in `all()` call so it actually checks all excs
  are `TransportClosed` instead of just creating an unused
  generator.

Gud Boi 592d918394 Tweak `test_inter_peer_cancellation` for races
Adjust `basic_echo_server()` default sequence len to avoid the race
where the 'tell_little_bro()` finished streaming **before** the
echo-server sub is cancelled by its peer subactor (which is the whole
thing we're testing!).

Deats,
- bump `rng_seed` default from 50 -> 100 to ensure peer
  cancel req arrives before echo dialog completes on fast hw.
- add `trio.sleep(0.001)` between send/receive in msg loop on the
  "client" streamer side to give cancel request transit more time to
  arrive.

Also,
- add more native `tractor`-type hints.
- reflow `basic_echo_server()` doc-string for 67 char limit
- add masked `pause()` call with comment about unreachable
  code path
- alphabetize imports: mv `current_actor` and `open_nursery`

Gud Boi 50f40f427b Include `TransportClosed` in tpt-layer err handling
Add `TransportClosed` to except clauses where `trio`'s own
resource-closed errors are already caught, ensuring our
higher-level tpt exc is also tolerated in those same spots.
Likely i will follow up with a removal of the `trio` variants since most
*should be* caught and re-raised as tpt-closed out of the `.ipc` stack
now?

Add `TransportClosed` to various handler blocks,
- `._streaming.MsgStream.aclose()/.send()` except blocks.
- the broken-channel except in `._context.open_context_from_portal()`.
- obvi import it where necessary in those ^ mods.

Adjust `test_advanced_faults` suite + exs-script to match,
- update `ipc_failure_during_stream.py` example to catch
  `TransportClosed` alongside `trio.ClosedResourceError`
  in both the break and send-check paths.
- shield the `trio.sleep(0.01)` after tpt close in example to avoid
  taskc-raise/masking on that checkpoint since we want to simulate
  waiting for a user to send a KBI.
- loosen `ExceptionGroup` assertion to `len(excs) <= 2` and ensure all
  excs are `TransportClosed`.
- improve multi-line formatting, minor style/formatting fixes in
  condition expressions.

Gud Boi bf6de55865 Improve tpt-closed msg-fmt/content and CRE case matching
Refine tpt-error reporting to include closure attribution (`'locally'`
vs `'by peer'`), tighten match conditions and reduce needless newlines
in exc reprs.

Deats,
- factor out `trans_err_msg: str` and `by_whom: str` into a `dict`
  lookup before the `match:` block to pair specific err msgs to closure
  attribution strings.
- use `by_whom` directly as `CRE` case guard condition
  (truthy when msg matches known underlying CRE msg content).
- conveniently include `by_whom!r` in `TransportClosed` message.
- fix `'locally ?'` -> `'locally?'` in send-side `CRE`
  handler (drop errant space).
- add masked `maybe_pause_bp()` calls at both `CRE` sites (from when
  i was tracing a test harness issue where the UDS socket path wasn't
  being cleaned up on teardown).
- drop trailing `\n` from `body=` args to `TransportClosed`.
- reuse `trans_err_msg` for the `BRE`/broken-pipe guard.

Also adjust testing, namely `test_ctxep_pauses_n_maybe_ipc_breaks`'s
expected patts-set for new msg formats to be raised out of
`.ipc._transport`.
