fix(client): 退出 Pangolin 时拆隧道(停内核),不再残留 sing-box/TUN
此前真退出(托盘退出 / Cmd+Q)走 windowManager.destroy(),从不先停内核, 而 sing-box 是 sudo root 子进程不随父进程退出 → 孤儿 + TUN 残留,得手动 pkill。 - system_tray:托盘「退出」前 await onBeforeQuit()(停内核)再 destroy。 - main:PangolinApp→ConsumerStatefulWidget,AppLifecycleListener.onExitRequested 在 Cmd+Q 时先停内核再退;_teardownVpn 调 vpnBridge.stop()(SIGTERM→sing-box, 拆 TUN),带 3s 超时兜底。 - 关窗口→隐藏托盘的路径不拆(保持连接,符合常驻语义)。 flutter analyze 0 error;116 tests passed。 Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
