MeowOS-For-R3P2/patch_v2/ncm_app/app/app.c

/* app.c — dev.player.ncm 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。页面切换统一走 meow_view_page_push/pop/replace。
 * 播放线程（player_manager）+ 媒体会话 IPC 线程（ipc_media）在 main 起动、退出时停。
 *
 * 铁律（APPS.md §3.4.1）：物理键禁映射——on_key 不处理任何键语义；返回=左缘左滑/返回钮/request_exit。
 * 左缘返回：播放页→歌单→主页→退出（登录页→退出）。
