React 19 compiler auto-optimizes memoization, making manual hooks unnecessary.
Changes:
- Remove ~60 useCallback/useMemo across 16 files
- Remove React.memo from nav-button and return-button
- Simplify hydration with useSyncExternalStore (privacy-provider)
- Add CHANGELOG.md for version tracking
No functional changes - internal optimization only.
