/* app.c — files 应用装配层：main + 组装 + 事件分发。
|
||
*
|
||
* 职责（对齐 hello_app/app.c）：main 只做初始化/建页/跑事件循环/清理；把 meow_ui_run 的平铺输入
|
||
* 回调（key/tap/swipe/tick/touch）路由到当前活动页（browser/viewer）；通用长按走独立注册
|
||
* （meow_ui_set_long_press_cb，§6.3）路由到 browser。页面切换统一走
|
||
* meow_view_page_push/pop（活动栈 + on_enter/on_leave 唯一驱动）。
|
||
*
|
||
* 铁律（APPS.md §3.4.1 / WORK_STATE.md）：物理键禁映射——不处理任何 key 语义；返回=左缘左滑
|
||
* （on_swipe LEFT）/返回钮/meow_ui_request_exit。目录进退不换页（browser 改 cur_dir 重扫）；
|
||
* 文本预览换页（push ACT_VIEWER）。退出=在根目录左滑或 SIGTERM（看门狗）。
