# 功能:
#   status            查看当前状态
#   engine <名称|URL> 把当前引擎槽位替换为指定搜索引擎（bing/baidu/360/douyin/sogou/google/自定义URL）
#   browser <名称>    修改跳转目标浏览器（via/chrome/edge），mi=恢复原版跳转逻辑
#   restore <目标>    回滚（engine=恢复引擎配置 browser=恢复原版APK all=全部）
#   refresh-backup    重新备份当前 APK（OTA 升级后执行）
# 无参数运行进入交互菜单。需要 root（KernelSU/Magisk）。
