/**
 * 浮层提示的外壳级接线：`ProjectChat` 发一条运行提示，工作台壳真的把它渲染成浮层；
 * 原来那一行状态栏（进行中进度、失败结论、取消回显）也走同一条通道，页面上不留那一行。
 *
 * 单测（`launcherNoticeToast`）只证明组件本身，`previewActivation` 只证明 App 会调这条通道；
 * 从「通道被调用」到「用户看到 toast」之间还差一层壳的接线（prop 名、handler、portal 挂点、
 * tone 传递）。这里用替身聊天把这一层单独钉住：以后有人把 `<LauncherNoticeToast/>` 挪进条件
 * 分支、或在传 prop 时写错名字，这条会红。
