Add error handling and documentation to event subscriptions based on
Copilot review feedback.
Changes:
- Added try-catch blocks to all event callbacks for graceful error handling
- Added comments documenting that subscriptions persist for app lifetime
- Improved JSDoc for onPatternDeleted function with lifecycle details
- Added error logging to help debug potential issues
Benefits:
- Prevents silent failures in event callbacks
- Clear documentation about subscription lifecycle
- Better developer experience with error messages

Replace direct store imports and calls with a Zustand-based event system
for decoupled cross-store communication.
Changes:
- Created storeEvents.ts using Zustand for event management
- Removed direct usePatternStore import from useMachineStore
- Removed dynamic imports for useMachineUploadStore and useMachineCacheStore
- Added event subscriptions in usePatternStore, useMachineUploadStore, and useMachineCacheStore
- useMachineStore now emits patternDeleted event instead of calling other stores directly
Benefits:
- Stores can be tested in isolation
- No tight coupling between stores
- Clear, explicit event-driven data flow
- Uses Zustand's built-in subscription system
- Easier to refactor stores independently

Split the 570-line useMachineStore into three focused stores for better
separation of concerns and improved re-render optimization:
**New Stores:**
- useMachineUploadStore (128 lines): Pattern upload state and logic
- useMachineCacheStore (194 lines): Pattern caching and resume functionality
- useMachineStore (reduced to ~245 lines): Connection, status, and polling
**Benefits:**
- Components only subscribe to relevant state (reduces unnecessary re-renders)
- Clear separation of concerns (upload, cache, connection)
- Easier to test and maintain individual stores
- 30% reduction in main store size
**Technical Details:**
- Uses dynamic imports to avoid circular dependencies
- Maintains all existing functionality
- Updated FileUpload, PatternCanvas, and App components
- All TypeScript compilation errors resolved
- Build tested successfully
Implements conservative 2-store extraction approach from issue #31.
