fix: add missing pointer event handlers for selection and drawing tools

Fixed multiple tools that were not working due to missing pointer event handlers:

**Selection Tools (rectangular, elliptical, lasso, magic-wand):**
- Added pointer move handler to draw selection preview while dragging
- Added pointer up handler to finalize selection and update selection store
- Selection tools now show live preview and create selections correctly

**Drawing Tools (clone, smudge, dodge/burn):**
- Added clone, smudge, and dodge to pointer up handler
- These tools now properly capture state changes in history
- Canvas re-renders correctly after using these tools

All affected tools now have complete pointer event handling:
- onPointerDown: Initialize tool state
- onPointerMove: Update preview/drawing while pointer is down
- onPointerUp: Finalize changes and update history
