.SYNOPSIS
    清听真机自检：安装最新 debug APK，冷启动，抓 logcat，校验 libmpv 是否只有单实例。

.DESCRIPTION
    判定依据：
      - 冷启动后 "PlaybackService 单例创建" 只出现一次；
      - 日志里出现过的 serviceId 只有 1 个；
      - media_kit Player 的 hashCode 只有 1 个。

.EXAMPLE
    powershell -ExecutionPolicy Bypass -File tools\device-check.ps1
    powershell -ExecutionPolicy Bypass -File tools\device-check.ps1 -DeviceId 192.168.3.2:36569
