"""剪贴板注入公共模块（ClipInject APK 通道）。
|
||
|
||
背景：Android 10+ 禁止后台（atx-agent/shell）写剪贴板——u2.set_clipboard
|
||
调用"成功"但内容被系统静默丢弃（Android 12/13 实测）。ClipInject
|
||
（com.example.clipinject，用户自研 APK）通过 am start 启动透明 Activity，
|
||
窗口聚焦后 setPrimaryClip；shell 身份启动 Activity 不受后台启动限制
|
||
（广播方式在 MIUI 会被 Background activity start 拦截，必须用 am start）。
|
||
|
||
工具页（web/tools_api.py）与任务执行器（tasks/generic/task.py）共用本模块。
