Major changes: - TUN mode: tun2socks + xray SOCKS architecture (replaced sing-box) - Hot-swap: node switching keeps TUN alive, only restarts xray - Traffic graph: live QPainter chart on dashboard with detail dialog - Settings: stock qfluentwidgets cards (SpinBox, ColorPicker, PushSettingCard) - Navigation: fixed icon/text overlap in expanded menu - Ctrl+V import, copy link from context menu - System proxy cleanup on exit (atexit safety net) - Build: data/ backup/restore during PyInstaller rebuild - Log throttling in TUN mode to prevent UI freeze Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
