/**
 * probe-dump.js — 把当前屏幕的控件树完整 dump 到一个文本文件
 *
 * 为什么不用 `uiautomator dump`：TikTok 的页面一直在动（视频、动画），
 * uiautomator 等不到 idle state 就直接失败（实测 "could not get idle state"）。
 * 而 AutoX 的无障碍读取不需要 idle，且**与引擎最终用的是同一套读取路径** ——
 * 探针看到的和引擎将来看到的完全一致。
 *
 * 用法：adb 启动本脚本，几秒后读 /sdcard/tiktok_app/probe-dump.txt
