Bug Fixes

• profiling: This fix resolves an issue where the lock profiler's wrapper class did not support PEP 604 type union syntax (e.g., asyncio.Condition | None). This was causing a TypeError at import time for libraries such as kopf that use union type annotations at class definition time.

• Fix for potential crashes at process shutdown due to incorrect detection of the VM finalization state when stopping periodic worker threads.
