Patch Changes

• Fix: Notify framework when count changes to update getTotalSize() (#1085)

  Fixed an issue where getTotalSize() would return stale values when the count option changed (e.g., during filtering or search operations). The virtualizer now automatically notifies the framework when measurement-affecting options change, ensuring the UI updates correctly without requiring manual useMemo workarounds.

  Before: When filtering items, the list container would maintain its previous height, causing excessive blank space (when count decreased) or inaccessible items (when count increased).

  After: Height updates automatically when count changes, providing the correct user experience.

  This fix applies to all framework adapters and has minimal performance impact (< 0.1ms per change).
