auto-claude: subtask-3-1 - Memoize touch handlers and getCurrentPageItems in Experience.tsx

- Added useCallback import from react
- Memoized handleTouchStart with empty dependency array
- Memoized handleTouchMove with empty dependency array
- Memoized handleTouchEnd with dependencies [touchStart, touchEnd, currentPage, totalPages]
- Memoized getCurrentPageItems with dependencies [experiences, currentPage, itemsPerPage]
- Follows patterns from BlogPost.tsx and ScrollContext.tsx reference files
