🧪 Testing Improvement: AmbientBiotaDirector Error Path

[marko1olo]

🎯 What: Missing error test for TryEnsureGraphicsResourcesCold in AmbientBiotaDirector.
📊 Coverage: The exception path during graphics resource buffer allocation is now tested by explicitly forcing a buffer size exception (using int.MaxValue), verifying that the system catches the Unity ArgumentException and safely returns false rather than crashing the tick update loop.
✨ Result: Improved test coverage for AmbientBiotaDirector, validating that system resource stress/out-of-bound errors are cleanly caught and handled during graphics payload execution.
