/* meowpanel.c — MeowOS Web 面板后端（MeowPanel）。
|
||
*
|
||
* 定位（MEOWPANEL_DESIGN §1/§2）：外置于 TF 卡 `MeowOS/opt/MeowPanel/` 的系统组件
|
||
* （HTTP/JSON 后端 + 前端静态托管），由 meow_svcd 读 TF 卡 `MeowOS/services.d/meowpanel.conf`
|
||
* 启动、meow_sysui 监管。**不进固件**；无卡时系统核心绝不对它有任何依赖。
|
||
*
|
||
* 架构（MEOWPANEL_PROTOCOL §1/§2 + SYSTEM_FRAMEWORK_SERVICES §4）：
|
||
* - 单进程单线程 + poll 串行处理（面板访问量极小）；内嵌 HTTP server。
|
||
* - 读侧（/api/status,/api/perf,/api/system）经 meow_svc_perf IPC（MSG_PERF_QUERY→RESULT）
|
||
* 聚合，**绝不各自爬 /proc**（单一权威源）。
|
||
* - 动作侧（/api/system/{reboot,shutdown,ota}）经 meow_svc_power IPC（MSG_POWER_ACTION→STATUS），
|
||
* 不再直连 poweroff/写 mtd5。
|
||
* - 设置镜像（/api/settings*,/api/theme*）直接读写板载 /usr/data/meow/settings.conf——
|
||
* **与 meow_ui_vol_read / meow_svc_power settings_get_int_trim 同款解析**（'=' 切分 +
|
||
* key 去首尾空白精确匹配；写用 "key = value\n"）。后端是独立进程，无法链接 launcher 内的
|
||
* meow_settings_*（那是 launcher 进程内存表），故直接镜像文件，保持同一存储契约。
|
||
* - 文件/应用/日志/通知：白名单根 /usr/data/mnt/sd_0 下 MeowOS/Music/MeowData/MeowAPPs/book。
|
||
*
|
||
* 编译（mipsel 静态）：build_meowpanel.sh；宿主编译 build_meowpanel.sh host。
|
||
* 依赖：仅 POSIX + libc（含 linux/input.h 内核头），零第三方库。设备无 python3/lua。
