- SDK §6.1 三层控件模型: Activity栈(push/pop/active) + 页面控件归属 owner + meow_ui_global_* 骨架(②) + 系统级仅内部接口(③) - meow_widget 加 owner; live_btn_hit/meow_widget_hit 仅 active activity 命中; touch_refresh stale 保护 - 根治"全屏页触摸主页按钮闪现"(跨页面控件残留); 控件对象复用弹栈不重建 - hello 迁移双 Activity(home/full): 全屏左滑=弹栈回主页, 根左滑=退出 - agent-119 按钮去圈(纯色accent+黑12/24%)+即时局部重绘保留; agent-121 SDK模板§5.3-5.7

/*
|
||
* meow_ui_global.c — App 跨 Activity 控件（§6.1 ②，SDK 托管骨架）。
|
||
*
|
||
* SDK 维护一个全局控件列表（钉在 App 的 Activity 栈之上、跨 Activity 常驻）：
|
||
* - 渲染：meow_ui_gfx present() 每帧在 active activity 内容之上、全局状态栏之下调
|
||
* meow_ui_global_render()（遍历列表调 render_cb）;
|
||
* - 触摸：meow_ui_input TAP 分发先给 meow_ui_global_hit(x,y)——命中返回 1=消费，
|
||
* 否则落到 active activity 页面控件（①）。
|
||
*
|
||
* 骨架（待 B2 细化）：无 z 序细分/无按压态管理/无命中区排布——App 的 render/hit 回调
|
||
* 自行决定绘制与命中。跨 Activity 常驻由「列表不随 Activity 栈变化」天然保证。
