youknowdot 1052e613ed Preserve interpreter-boundary diagnostics and syslog restrictions (#9365)
* Preserve Unicode in thread unraisable messages

Keep the callable representation as WTF-8 for unraisable hooks and audit callbacks. Preserve the existing String entry point and stderr fallback; this does not claim lossless stderr rendering.

Assisted-by: OpenAI Codex:model unavailable

* Use the WTF-8 string conversion constructor

Use the existing From<&str> implementation to copy the message prefix without changing Unicode semantics.

* Preserve cross-interpreter marshal error causes

Wrap failures from existing code/function serialization helpers as NotShareableError, matching the CPython 3.15 marshal boundary while retaining the original exception cause. No new test C API or lifecycle behavior.

* Enforce syslog interpreter boundaries and sync queue cleanup

Reject subinterpreter openlog/closelog before audit or host mutation, and
reject implicit syslog opening after audit when the process logger is not
already open, matching CPython 3.15 guard placement and error text.
Already-open logging and setlogmask remain unchanged.

Migrate concurrent/interpreters/_queues.py through scripts/update_lib to
CPython d220409a13b77de7a6c30abe16ea90db01528edc, removing unused eager
pickle import and exception targets. Native serialization imports pickle
on demand; module import timing and debug locals may nevertheless differ.

No new fixtures or interpreter lifecycle mechanisms are introduced.
