refactor(hello): 视图框架批次② — hello.c 拆分为 app.c+ui/{home,full,demo}.c+ui/common/chrome.c+logic/{notify,state}.c（定案B: demo视图态留ui/；定案b: page导航包装activity栈）；test_p1p2p3_repro 改多文件链接形态 (agent-177)

hello f45ba051→c06b3b4f; mipsel -Wall -Wextra 0 warning; 宿主 P1c/P2/P3+widgets 全 PASS 出入(诚实): view on_draw/on_event 路径暂未启用(注册表直绘已覆盖, on_draw 双画风险), 留批③实测; home/full 仍手绘未迁注册表

+/* app.c — hello 应用装配层：main + 组装 + 事件分发。
+ *
+ * 职责（SDK_VIEW_FRAMEWORK_DESIGN.md §B.2）：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（home/full/demo）。
+ * 页面切换统一走 meow_view_page_push/pop（活动栈 + on_enter/on_leave 的唯一驱动，App 不再
+ * 分别调 activity_push/pop）。业务变化经 logic 监听器送回 UI（见 ui/home.c）。
+ *
+ * 契约（MEOW_APP_SDK.md §1/§3/§6）：应用只调 meow_ui API。
