fix: CollectionView not updating when parent rebuilds with new data

Added didUpdateWidget override to reset _syncDataInitialized flag on
parent rebuilds, restoring filtering/search behavior broken in v7.16.0
while preserving stateActions functionality.

Added 29 tests for CollectionView and CollectionItem.

+### Fixed
+
+* **CollectionView not updating when parent rebuilds with new data** - Sync data callbacks (e.g. `data: () => _filteredList`) were only read once due to `_syncDataInitialized` flag introduced in v7.16.0, breaking filtering/search patterns. Added `didUpdateWidget` override to reset the flag on parent rebuilds while preserving `stateActions` behavior
+
+### Added
+
+* **CollectionView test coverage** - Added 29 tests covering `CollectionItem` helpers, sync/async data, empty states, headers, spacing, transform/sort, separated/grid layouts, parent-driven data updates, and configuration options
