* feat: migrate logs API from REST to IPC streaming
- Replace REST API `/logs` calls with IPC streaming implementation
- Add new `src-tauri/src/ipc/logs.rs` with `LogsMonitor` for real-time log streaming
- Implement duplicate stream prevention with level tracking
- Add frontend-backend communication via Tauri commands for log management
- Remove WebSocket compatibility, maintain IPC-only mode
- Fix duplicate monitoring task startup when toggling log service
- Add proper task lifecycle management with JoinHandle cleanup
* refactor: remove dead code from logs.rs to fix clippy warnings
- Remove unused `timestamp` field from LogItem struct
- Remove unused `client` field from LogsMonitor struct
- Remove unused methods: `is_fresh`, `get_current_monitoring_level`, `get_current_logs`
- Simplify LogsMonitor initialization by removing client dependency
- All clippy warnings with -D warnings now resolved
* refactor: extract duplicate fmt_bytes function to utils module
- Create new utils/format.rs module with fmt_bytes function
- Remove duplicate fmt_bytes implementations from traffic.rs and memory.rs
- Update imports to use shared utils::format::fmt_bytes
- Add comprehensive unit tests for fmt_bytes function
- Ensure DRY principle compliance and code maintainability
✨ **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
fix: add missing showNotice error handling and improve async UI feedback
- Add showNotice error notifications to unlock page async error branches
- Restore showNotice for YAML serialization errors in rules/groups/proxies editor
- Ensure all user-facing async errors are surfaced via showNotice
- Add fade-in animation to layout for smoother theme transition and reduce white screen
- Use requestIdleCallback/setTimeout for heavy UI state updates to avoid UI blocking
- Minor: remove window.showNotice usage, use direct import instead
- Improve config validation process with detailed logging and error tracking
- Add more robust error handling in profile updates and config patches
- Implement comprehensive config validation using clash core subprocess
