- 新增 WinTun TUN 设备实现(tun_windows.go),无需安装驱动, wintun.dll 嵌入 exe 运行时自动释放 - 新增 Windows 路由管理(route_windows.go),使用 route/netsh 命令 - 新增 Windows 路径(paths_windows.go),使用 %APPDATA%/%LOCALAPPDATA% - 拆分 daemon 启动逻辑:launch_unix.go(Setsid) / launch_windows.go (CREATE_NEW_PROCESS_GROUP),公共代码提取到 launch_common.go - 拆分提权逻辑:elevation_darwin.go(osascript) / elevation_windows.go (ShellExecute UAC) / elevation_other.go(pkexec) - IPCSocketPath 按平台分散,Windows 用 %TEMP%\lmvpn.sock - daemon 二进制名用编译时常量(daemonBinaryName),按平台选定 .exe 后缀 - Makefile 新增 build-windows 目标 - 重新标记 !darwin 文件为 !darwin && !windows
