AnimationGroup<TKey> class
Shared animation controller for bulk expand/collapse operations.
Uses an AnimationController for smooth forward/reverse transitions.
- controller.value represents visibility: 0 = hidden, 1 = visible
- forward() for expanding, reverse() for collapsing
- Interrupting just changes direction, value continues smoothly
