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.

Fix TypeScript compilation error by allowing tool loader to accept both
ToolType and internal tool keys (like 'rectangular-select').
Changes:
- Change function parameter from ToolType to string internally
- Update getTool() to accept ToolType | string
- Update preloadTool() to accept ToolType | string
- Update isToolLoaded() to accept ToolType | string
- Add documentation about supporting internal tool keys
This resolves the build error where 'rectangular-select' was not
assignable to ToolType, while maintaining type safety at the public API.

The canvas container's pointer handler was capturing ALL events when the text
tool was active, including clicks on the text editor UI (overlay, textarea,
handles). This prevented text selection, click-outside commit, and text
dragging from working.
Now the handler checks if the on-canvas editor is already active and returns
early, allowing the OnCanvasTextEditor to handle its own events properly.
Fixes:
- Text selection now works in textarea
- Clicking outside editor commits text
- Dragging transform handles moves text

DrawCommand was correctly restoring canvas state but wasn't triggering
React re-renders, causing the UI to appear unchanged. Added updateLayer()
calls with timestamp updates to both execute() and undo() methods to
ensure proper re-rendering after canvas modifications.

Critical Fix - Move Tool Undo/Redo:
- Create MoveCommand class to track layer position changes
- Capture initial and final positions during move operation
- Only add to history if position actually changed
- Real-time visual feedback during drag (via updateLayer)
- Single undo point per move operation (not per pixel)
Command Pattern:
- MoveCommand extends BaseCommand
- Implements execute() and undo() methods
- captureAfterPosition() called on pointer up
- hasChanged() prevents no-op entries in history
Files:
- core/commands/move-command.ts - New command class
- tools/move-tool.ts - Updated to use MoveCommand
- core/commands/index.ts - Export MoveCommand
This fixes the critical issue where moving layers had no undo support.
Users can now undo/redo layer movements as expected.
