// 单元测试：挂载/卸载/链接/取消链接 OPT 容器
// 需要管理员权限运行（驱动安装+挂载都需要）
//
// 用法:
//   test_mount_opt mount  <opt_path> <tag>           挂载容器，验证设备可访问
//   test_mount_opt unmount <tag>                     卸载容器，验证设备已消失
//   test_mount_opt link   <tag> <link_dir>           为已挂载的卷创建目录链接(Junction)
//   test_mount_opt unlink <link_dir>                 移除目录链接(Junction)
//
// 示例:
//   test_mount_opt mount  "C:\Users\aiyah\Desktop\SDGA_A011_20260716114938_0.opt" OPT_TEST
//   test_mount_opt link   OPT_TEST "C:\mnt\opt_test"
//   test_mount_opt unlink "C:\mnt\opt_test"
//   test_mount_opt unmount OPT_TEST
