Gud Boi	8724cc3915	Fix dropped `for/else` re-raise in masking CM `30e15925` ("Add `start_or_cancel()` to `trionics._taskc`") inserted `async def start_or_cancel()` — whose body opens its own col-4 `try:` — immediately before the trailing `else: raise`. Because the edit was a pure insertion (0 deletions), the same `else: raise` lines were silently REPARENTED: they used to be the `for exc_match in matching: ... else: raise` of `maybe_raise_from_masking_exc`, but now bind to `start_or_cancel`'s `try/except` where they're unreachable dead code. Net effect: `maybe_raise_from_masking_exc` lost the `for/else` re-raise of the un-masked exception, so a masked child cancellation gets swallowed instead of surfaced. - restore the `for/else: raise` to `maybe_raise_from_masking_exc` - drop the now-dead `else: raise` from `start_or_cancel` Surfaced as 2 deterministic failures in `test_sigint_closes_lifetime_stack[wait_for_ctx-bg_aio_task- send_SIGINT_to=child-*]` (the SIGINT-to-child "silent-abandon" regime). Bisected with `trio` held at `0.29.0`: clean at `9c36363b` (0/8), broken at `30e15925` (8/8), fixed (0/8). NOT a `trio` (0.29↔0.33 identical) nor logging-plugin regression.

Gud Boi	1c0ddc373a	Add `start_or_cancel()` to `trionics._taskc` Wrapper around `trio.Nursery.start()` that DOESN'T mask out-of-band cancellation as a lossy startup failure. Picks the right re-raise: ambient `Cancelled` when present, the genuine startup-protocol `RuntimeError` otherwise. The problem, - `trio.Nursery.start()` raises a generic `RuntimeError("child exited without calling task_status.started()")` whenever the started task exits BEFORE calling `task_status.started()` — INCLUDING the common case where the child was cancelled out-of-band by an ancestor cancel-scope erroring/cancelling. - In that case the original `trio.Cancelled` is swallowed and the caller is left w/ an opaque, root-cause-detached `RuntimeError`. The fix, - Catch the "...started" RTE. - `await trio.lowlevel.checkpoint_if_cancelled()` — re-raises the in-flight `Cancelled` IFF we're under effective cancellation (ancestor-inclusive), carrying trio's auto-generated reason which points at the true root exc. - If we're NOT cancelled the `checkpoint_if_cancelled()` is a cheap no-op and we fall through to re-raise the genuine startup-protocol RTE. Re-export from `tractor.trionics` so callers don't have to reach into `_taskc`.

Gud Boi	ac3bc11332	Add per-actor `setproctitle` via `devx._proctitle` New `tractor.devx._proctitle` mod sets each sub-actor's `argv[0]` (and kernel `comm`) to `tractor[<aid.reprol()>]` — e.g. `tractor[doggy@1027301b]` — so `ps`/`top`/`htop` and `acli.pytree`/reaper tooling can identify actors at a glance without parsing full cmdlines. Deats, - `set_actor_proctitle()` wraps the `setproctitle` pkg with `ImportError` guard; optional at runtime but listed in `pyproject.toml` so default installs benefit. - called early in `_child._actor_child_main()` after `Actor` construction, before `_trio_main()` entry. - tests in `tests/devx/test_proctitle.py`: format unit test, `/proc/{cmdline,comm}` integration test, negative detection test.

Gud Boi	15b8bd27ae	Split py-version-gated uv dependency-groups Reshuffle `pyproject.toml` deps into per-python-version `[tool.uv.dependency-groups]`: - `subints` group: `msgspec>=0.21.0`, py>=3.14 - `eventfd` group: `cffi>=1.17.1`, py>=3.13,<3.14 - `sync_pause` group: `greenback`, py>=3.13,<3.14 (was in `devx`; moved out bc no 3.14 yet) Bump top-level `msgspec>=0.20.0` too.
