Added: Animation: Added AnimationEventInfo ref struct as a non-allocating alternative parameter for animation event callbacks. This new stack-allocated struct eliminates garbage collection overhead when handling animation events, providing significant performance benefits for animation-heavy scenes. AnimationEventInfo provides read-only access to all animation event parameters and state information from both Animator and legacy Animation components. Existing AnimationEvent callbacks remain fully backwards compatible.
