- Implemented ScrollOffsetPreferenceKey for performance-optimized scroll tracking
- Added invisible GeometryReader at top of ScrollView to track offset
- Replaced onScrollGeometryChange + onScrollPhaseChange with onPreferenceChange
- Removed currentScrollOffset and scrollViewHeight state variables
- Continuous tracking with 3% threshold check in onPreferenceChange
- Updated JumpButton to receive containerHeight as parameter
PreferenceKey approach is more performant than onScrollGeometryChange:
- Single preference update instead of multiple geometry changes
- Direct access to scroll coordinate space
- Simpler state management with lastSentProgress threshold
