Windows 与 macOS 桌面同路线：Flutter 应用 + sing-box.exe 子进程 + wintun TUN
接管整机流量。Dart/桥接层此前已 Windows-ready（kernel_process._buildCommand /
_resolveBinaryPath、desktop_vpn_bridge 配置路径、fetch-desktop-bin.sh），本次补
原生外壳 + 提权 + 打包：
- flutter create --platforms=windows 生成 windows/ runner（flutter_secure_storage
已注册 windows 插件，token 存储可用）。
- runner.exe.manifest 设 requestedExecutionLevel=requireAdministrator：启动 UAC
提权，sing-box 子进程继承管理员权以创建 wintun TUN（与 _buildCommand 既有设计一致）。
- windows/CMakeLists.txt 增 install 规则：打包时把 app/kernel/dist/desktop/windows-*/
{sing-box.exe,wintun.dll} 拷到 app exe 同级目录（存在才拷，缺失告警，类比 android
build.gradle 占位）。
- kernel_process.dart 启动时校验 wintun.dll 与 sing-box.exe 同目录，缺失早警。
- windows/README.md：拉内核二进制 / 管理员终端 flutter run / 打包 / 出网验证步骤。
提权用 requireAdministrator（每次 UAC），正式版可换特权 helper（BACKLOG，类比 SMJobBless）。
本机（macOS）验证：flutter analyze 无 error。Windows 真机 build/连通验证待后续
（无 Windows 机器，状态同 Android/iOS：代码就绪、未真机验证）。
