/* hello.c — MeowOS SDK 版示例应用（链 meow_ui.a，B1）。
|
||
*
|
||
* 契约（MEOW_APP_SDK.md §1/§3/§6）：应用只调 meow_ui API —— 屏幕（back_buf +
|
||
* flush 上屏）与输入（meow_ui_run 事件循环）由框架接管；不再 open/mmap/ioctl
|
||
* /dev/fb0、不再读 /dev/input/event*。本应用验证「清屏 + 画文本 + 画按钮 +
|
||
* 响应触摸」这一最小工作闭环，并集成了通知触发按钮（meow_notify_send，§9.1）
|
||
* 用于端到端测试通知链路（SDK → IPC → launcher 中央存储 → 10s TTL 落盘）。
|
||
*
|
||
* 交互：
|
||
* - 点按钮 → tap 计数 +1（按钮标签实时更新）；
|
||
* - 通知触发行（6 个按钮）：每个点击 meow_notify_send() 发一条不同参数的通知，
|
||
* 覆盖 普通INFO / 媒体(单例) / HIGH紧急度 / 进度(40%) / 常驻 / 跳转Activity；
|
||
* - CANCEL LAST 按钮：meow_notify_cancel(最近一次 send 的 id)；
|
||
* - 左缘左滑（抬手触发）→ 请求退出（回应用列表）；滑动过程顶部出现随位移增长的进度条；
|
||
* - 空闲时 on_tick 每秒刷新一行状态（含运行秒数）。
|
||
*
|
||
* 宿主/qemu 离屏：设 MEOW_UI_DUMP=<ppm 路径> 时，首帧 flush 即把 back_buf 写成
|
||
* PPM 截图供检查；设备上无副作用。
|
||
*
|
||
* Build（见 build_hello.sh）：
|
||
* zig-mipsel-cc -Os -static hello.c meow_ui.a libz.a -lpthread -o hello
