`SendStream.send_all()` can raise `trio.Cancelled` after writing an
arbitrary prefix of the four-byte length header and payload. The
peer can no longer distinguish a following msg boundary.
Close the stream under a shield before propagating cancellation so
callers can not append another msg to an indeterminate byte stream.
Caught-during: review remediation
Found-via: prospective P2 cancellation review

Linux previously accepted a pre-existing runtime bindspace without
checking its owner or mode, even though Darwin enforced both. Share
the POSIX directory guard so every managed root and subdir rejects
non-directories and foreign UIDs before changing permissions.
Normalize owner-controlled bindspaces to `0o700` and add Linux
regressions for mode repair, foreign ownership, and non-directory
paths.

Darwin's pytest `tmp_path` can already exceed the 104-byte AF_UNIX
budget before appending either synthetic socket filename. That made
the new sentinel-policy regression fail identically in both macOS
matrix legs without exercising reaper behavior.
Allocate the test's real socket files under a short
`/tmp/tractor-reap-*` directory and retain scoped cleanup.

Moving Darwin sockets to `/tmp/tractor-<uid>` left pytest and the
standalone reaper searching only `XDG_RUNTIME_DIR`. Enabling that
shared bindspace naively would also let automatic session cleanup
unlink an independent live `registry@1616.sock`.
Resolve the runtime's actual default UDS bindspace on every platform.
Exclude the pid-less registry sentinel from automatic cleanup while
retaining explicit CLI removal, and document that destructive choice.
Cover bindspace resolution and automatic-vs-explicit sentinel policy.

`unlink_uds_bind_addrs()` reconstructs self-assigned socket paths
after a hard kill. An over-budget bindspace can make
`UDSAddress.get_sockname()` raise before the guarded `os.unlink()`,
replacing the original supervision outcome after the child is gone.
Catch and report reconstruction failures, then skip cleanup without
raising. Cover the overflow path and prove no unlink is attempted.

Actor names and custom runtime subdirs can otherwise produce unsafe
or overlong pathname sockets after moving Darwin's bindspace to
`/tmp`.
Deats,
- hash unsafe or over-budget actor names while retaining `@pid.sock`
- share deterministic naming with post-kill socket cleanup
- enforce Linux and Darwin `sun_path` byte budgets
- restore non-Darwin dir validation and mode `0700`
- validate every nested Darwin runtime-dir component

`platformdirs` can place the runtime dir deep below a pytest temp
home, pushing `registry@1616.sock` past Darwin's 104-byte
`AF_UNIX` limit.
Use a compact `/tmp/<app>-<uid>` root on Darwin and secure it
before allocating socket paths:
- require a real, current-user-owned dir via `lstat()`
- tighten existing roots to mode `0700`
- reject symlinks and unsafe nested dirs
Cover the path budget, mode, and symlink rejection.

Adjust all `tractor._state`, `tractor._addr`,
`tractor._supervise`, etc. refs in tests and examples
to use the new `runtime/`, `discovery/`, `spawn/` paths.
Also,
- use `tractor.debug_mode()` pub API instead of
`tractor._state.debug_mode()` in a few test mods
- add explicit `timeout=20` to `test_respawn_consumer_task`
`@tractor_test` deco call

Since it's merely a local-file-sys subdirectory and there should be no
reason file creation conflicts with other bind spaces.
Also add 2 test suites to match,
- `tests/ipc/test_each_tpt::test_uds_bindspace_created_implicitly` to
verify the dir creation when DNE.
- `..test_uds_double_listen_raises_connerr` to ensure a double bind
raises a `ConnectionError` from the src `OSError`.
