Add comprehensive Web Worker system for parallel filter processing:
**Web Worker Infrastructure:**
- Create filter.worker.ts with all image filter implementations

**UI Integration:**
- Update FilterPanel to use async filter processing
- Add loading states with descriptive messages ("Applying blur filter...")
- Add toast notifications for filter success/failure
- Non-blocking UI during heavy filter operations
**Performance Benefits:**

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.

- Error notifications for: failed operations
- Warning notifications for: unsupported file types
UI Features:
- Stacks toasts in top-right corner
- Color-coded by type with icons (CheckCircle, AlertCircle, AlertTriangle, Info)
- Accessible with ARIA attributes
- Smooth animations using custom CSS keyframes
This provides immediate user feedback for all major operations throughout
the application.
