🧪 Add test for AmbientBiotaDirector try-catch error handling

[marko1olo]

🎯 What: Adds a missing unit test to ensure that the try...finally block in AmbientBiotaDirector.Tick correctly releases pinned buffers when a scheduled job throws an exception.
📊 Coverage: Specifically covers the Tick_ThrowsException_ReleasesBufferPins path, injecting an invalid job execution context (Dispose() on a NativeArray) to force a throw in the job scheduler and verify the ReleaseBiotaJobBufferPins is executed in the finally block.
✨ Result: Improved test coverage and reliability for AmbientBiotaDirector's error handling and resource management.
