feat(powermgr): 期3 policy 生效 + 标定工具 + 模型单键 setter + events 说明
- policy：IPC 0xD2/0xD3 GET/SET（SET 动作级鉴权=root+系统身份，SO_PEERCRED→pid→exe→classify，同 svc_power） + CLI `meow_power policy show|set`。策略项 profile 四档(performance/balanced/powersave/ultra) + 低电阈值(power.low_pct/critical_pct 读 settings.conf) + 亮度上限(power.brightness_cap) + 息屏上限(power.screen_timeout_cap)。**默认全关**(profile=balanced 无操作=现状, cap=0 不生效, 只能用户手动开)。生效方式: powermgr 不直接写系统——只写 settings.conf power.* 键(原子), launcher/sysui 期4 消费; 本服务绝不 poke 背光/息屏/wlan0/bt。低电/极低阈值改从 settings.conf 读, 事件检测即时生效。 - calibrate：`meow_power calibrate start <场景>|stop|list`——守护内 2s 节拍采样 电流(mp2731 current_now)+亮度+CPU+wifi/bt 状态+电量%变化，写 TF MeowOS/logs/power_calib_<epoch>.csv (无卡降级 /tmp，逐行 fflush)，用户实验中 start/stop 两命令即可。 - model：`meow_power model set <key> <mw>` 读改写单键+原子写(tmp+rename)，守护每拍重载 conf。 - events：App 前后台切换——launcher MSG_ACT_FOCUS 为单向 app→launcher 上报，powermgr 侧无导出点 可接，诚实标注「期4 接 launcher」扩展，本期不编造该事件（延续期2 口径）。 - 验证：宿主+qemu 全量 76/76 PASS（期1/2 全过+新增 policy/calibrate/model-set 用例），mipsel 静态交叉 0 warning，二进制 151516B(<200KB 阈值)。md5 1ef2f8afc07acc7aa09dee9f7149aba8。
