r'''安装包完整验收：装 → 验 → 卸 → 再验。

用户要求"所有东西做完记得先测试能不能用"，所以每一步都实测。

⚠ 环境注意：
    我这个 shell **不是管理员**，而安装器会提升。
    所以所有"清理"动作都要交给**安装器/卸载器**自己做，
    不能靠 PowerShell 杀进程或删 Program Files（会拒绝访问）。

补丁历史（这轮修的四个真 bug）：
    1. --uninstall 里 Popen 不重定向 stdio -> capture_output 等管道 EOF -> "卡死"
    2. --uninstall 里 input() 无 stdin 时永久阻塞 -> 控制面板卸载卡死
    3. _kill_running 用 taskkill /IM ykxmz.exe 把自己也杀了
       -> 后面的删自启/删数据全没执行
    4. 安装器关不掉以管理员身份跑着的旧实例 -> "无法关闭应用程序" -> 安装回滚
       -> 改成 PrepareToInstall 里自己 taskkill /F
