feat: Complete frontend integration with native WebSocket and FastAPI backend
- Created websocket_client.js: Native WebSocket wrapper with Socket.IO-compatible interface - Automatic reconnection with exponential backoff - Room-based subscriptions for targeted updates - Message queueing during disconnection - Updated HTML templates (index.html, queue.html): - Replaced Socket.IO CDN with native websocket_client.js - No external dependencies needed - Updated JavaScript files (app.js, queue.js): - Added room subscriptions on WebSocket connect (scan_progress, download_progress, downloads) - Added dual event handlers for backward compatibility - Support both old (scan_completed) and new (scan_complete) message types - Support both old (download_error) and new (download_failed) message types - Support both old (queue_updated) and new (queue_status) message types - Registered anime router in fastapi_app.py: - Added anime_router import and registration - All API routers now properly included - Documentation: - Created FRONTEND_INTEGRATION.md with comprehensive integration guide - Updated infrastructure.md with frontend integration section - Updated instructions.md to mark task as completed - Testing: - Verified anime endpoint tests pass (pytest) - API endpoint mapping documented - WebSocket message format changes documented Benefits: - Native WebSocket API (faster, smaller footprint) - No external CDN dependencies - Full backward compatibility with existing code - Proper integration with backend services - Real-time updates via room-based messaging
