Implemented cached-context exit completion in
`tractor.trionics.maybe_open_context()`.
> `git diff HEAD~1..HEAD -- tractor/trionics/_mngrs.py`
The generated implementation adds `_CtxExit`, whose `done` event
publishes an `outcome.Outcome[None]`. `_Cache.run_ctx()` records either
`Value(None)` or `Error(exc)` after the resource exit attempt. The final
MOC consumer signals `no_more_users`, waits for completion under a
shielded cancel scope, removes the per-key lock, and unwraps the outcome
so ordinary cleanup failures are raised at the consumer boundary.
`trio.Cancelled`, `KeyboardInterrupt`, and `SystemExit` continue through
the service task rather than being converted into regular cleanup
errors.
> `git diff HEAD~1..HEAD -- tests/test_resource_cache.py`
The generated regressions cover successful exit blocking, cleanup-error
delivery, final-user cancellation, cancellation combined with a cleanup
error, and service-nursery cancellation. The existing teardown re-entry
test now uses explicit events instead of a ten-second cleanup sleep and
asserts that the replacement resource is a fresh cache miss.
Verification:
`env PYTHONPATH="$PWD" /home/goodboy/repos/tractor/py313/bin/python -m pytest tests/test_resource_cache.py`
Result: `16 passed in 8.37s`.
