feat(amsd): meow_amsd 活动管理器一期 + am CLI (agent-212, 用户定案) — svcd托管(trigger=boot); 生命周期注册表(状态/时长/退出码/信号/崩溃计数+历史环形); launcher launch/exit/stdout管道捕获上报(logcat式,崩溃尾巴drain不丢); am status/list/history/start/kill(root门); crash双保险转发; S89预置conf

+/* am.c — MeowOS 活动管理器用户侧 CLI（AMSD_DESIGN.md §3，安卓习惯，进固件 /usr/bin/am）。
+ *
+ * 连 amsd sock（--sock/MEOW_AMS_SOCK，默认 /usr/data/meow_ams.sock），发一条命令行，
+ * 读响应直到 EOF，格式化输出。root 免鉴权（读）；写操作（start/kill）一期仅 root/系统身份。
+ *
+ * 子命令：
+ *   am status                 → 在跑 App 表（pkg/状态/pid/运行时长/activity）
+ *   am list                   → 注册表 + 状态（pkg/name/state/pid/launches/crashes）
+ *   am history [pkg]          → 事件历史（每 App 最近 8 条；无 pkg=全部）
+ *   am start <pkg>[/<activity>] → 经 amsd→launcher 拉起
+ *   am kill  <pkg>            → 经 amsd→launcher 终止（SIGTERM 语义）
+ *
+ * 编译（mipsel 静态）：zig-mipsel-cc -Os -Wall -Wextra -static am.c -o am
+ * 宿主：gcc -Os -Wall -Wextra am.c -o am_host
