feat: Implement configuration caching mechanism and force-refresh feature**

✨ **New Features**:

* Added API and frontend support for forcibly refreshing Clash configuration cache
* Implemented a configuration cache TTL mechanism (60 seconds) to reduce redundant requests
* Introduced `ProxyRequestCache` system to manage backend data caching
* Automatically refresh frontend state after core operations to enhance user experience

🚀 **Performance Optimizations**:

* Increased Clash configuration refresh interval from 5 seconds to 60 seconds
* Force refresh cache after configuration updates to resolve data inconsistency
* Automatically trigger state refresh after core switch, start, stop, and restart actions

🔧 **Technical Improvements**:

* Removed unused dependencies: `ab_glyph`, `owned_ttf_parser`, `ttf-parser`
* Simplified WebSocket dependency management, unified `tungstenite` version
* Refactored configuration save validation process, improved merge file handling
* Improved error handling and overall user experience
