This commit includes several improvements and new features: - Updated the WebSocket connection logic in `websocket.py` to include connection status messages and periodic pings for maintaining the connection. - Introduced new skeleton components (`Skeleton.vue`, `SkeletonDashboard.vue`, `SkeletonList.vue`) for improved loading states in the UI, enhancing user experience during data fetching. - Refactored the Vite configuration to support advanced code splitting and caching strategies, optimizing the build process. - Enhanced ESLint configuration for better compatibility with project structure. These changes aim to improve real-time communication, user interface responsiveness, and overall application performance.
