TypeScript compilation fixes:
- Added modifier keys (altKey, ctrlKey, shiftKey, metaKey) to PointerState interface
- Updated all PointerState creations in canvas to include modifier keys
- Added 'smudge' and 'dodge' cursor definitions to tool store
Tool integration:
- Added 'clone', 'smudge', 'dodge' to drawing tools array in canvas
- Clone Stamp uses Alt+Click to set source point
- Dodge/Burn uses Alt key to toggle between dodge (lighten) and burn (darken) modes
- Smudge tool benefits from modifier key tracking for future enhancements
All tools now properly receive keyboard modifier state for advanced interactions.
Build verified successful with pnpm build.
