feature: Refactor useMachineStore into focused stores

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.
