feat(phase-13): implement layer masks foundation for non-destructive editing
Add comprehensive layer mask system with core functionality for non-destructive editing.
Features:
- LayerMask interface with canvas, enabled, and inverted properties
- Layer interface updated with mask property
- Full mask management in layer store:
* addMask() - Creates white mask (fully visible)
* removeMask() - Removes mask from layer
* toggleMask() - Enable/disable mask
* invertMask() - Invert mask values
* applyMask() - Apply mask to layer and remove
- Duplicate layer now clones masks
- Grayscale mask system (white=reveal, black=hide)
Changes:
- Updated types/layer.ts with LayerMask interface
- Modified Layer interface to include mask property
- Updated store/layer-store.ts:
* Added mask property initialization to createLayer
* Added 5 new mask management functions
* Updated duplicateLayer to clone masks

feat: implement Phase 2 - Core Canvas Engine with layer system
Complete canvas rendering infrastructure and state management:
**Type System (types/)**
- Layer interface with blend modes, opacity, visibility
- Canvas state with zoom, pan, grid, rulers
- Tool types and settings interfaces
- Selection and pointer state types
**State Management (store/)**
- Layer store: CRUD operations, reordering, merging, flattening
- Canvas store: zoom (0.1x-10x), pan, grid, rulers, coordinate conversion
- Tool store: active tool, brush settings (size, opacity, hardness, flow)
- Full Zustand integration with selectors
**Utilities (lib/)**
- Canvas utils: create, clone, resize, load images, draw grid/checkerboard
- General utils: cn, clamp, lerp, distance, snap to grid, debounce, throttle
- Image data handling with error safety
**Components**
- CanvasWrapper: Multi-layer rendering with transformations
- Checkerboard transparency background
- Layer compositing with blend modes and opacity
- Grid overlay support
- Selection visualization
- Mouse wheel zoom (Ctrl+scroll)
- Middle-click or Shift+click panning
- LayersPanel: Interactive layer management
- Visibility toggle with eye icon
- Active layer selection
- Opacity display
- Delete with confirmation
- Sorted by z-order
- EditorLayout: Full editor interface
- Top toolbar with zoom controls (±, fit to screen, percentage)
- Canvas area with full viewport
- Right sidebar for layers panel
- "New Layer" button with auto-naming
**Features Implemented**
✓ Multi-layer canvas with proper z-ordering
✓ Layer visibility, opacity, blend modes
✓ Zoom: 10%-1000% with Ctrl+wheel
✓ Pan: Middle-click or Shift+drag
✓ Grid overlay (toggleable)
✓ Selection rendering
✓ Background color support
✓ Create/delete/duplicate layers
✓ Layer merging and flattening
**Performance**
- Dev server: 451ms startup
- Efficient canvas rendering with transformations
- Debounced/throttled event handlers ready
- Memory-safe image data operations
Ready for Phase 3: History & Undo System
