/* test_np_keys.c — 宿主单测：Now Playing 播放页/歌词页物理键分发（Task C）。
 *
 * 背景（真机现象）：桌面播放页与歌词页上，音量键 + 播放键「完全无反应」。
 * 根因（now_playing.c）：run_now_playing() 原先只接播放键(164)与电源键，未接音量键
 * (114/115)，导致播放页/歌词页（同一循环，与页无关）调不了音量。
 *
 * 本测复现 run_now_playing() 的按键动作应用（np_apply_key_actions）：音量键走
 * settings_volume_adj(±step)、播放键走 meow_media_playctl（按会话当前态 1=播放 2=暂停）。
 * 断言：
 *   K1 音量减边沿 → settings_volume_adj(-step)；
 *   K2 音量加边沿 → settings_volume_adj(+step)；
 *   K3 播放键边沿 + 会话正在播放 → meow_media_playctl(2,0)（暂停）；
 *   K4 播放键边沿 + 会话已暂停 → meow_media_playctl(1,0)（播放）；
 *   K5 播放键边沿 + 无会话 → 不下发（空态不误报）；
 *   K6 无任何边沿 → 两个回调都不触发；
 *   K7 音量/播放边沿都会更新 last_input（自动息屏计时复位）。
 *
 * 编译（在 patch_v2/meow_launcherd 下）：
 *   gcc -Wall -Wextra -I../sdk -I. -ffunction-sections -fdata-sections \
 *       -Wl,--gc-sections -DMEOW_NP_KEYS_TEST \
 *       test_np_keys.c -o test_np_keys
 *   ./test_np_keys
 * 说明：now_playing.c 用 #include 同 TU 平移（惯例同 test_vol_ramp_jack）；-ffunction-sections
 *       + --gc-sections 只保留 np_apply_key_actions 及其依赖，其余（渲染/控件/绘制）被回收，
 *       故仅需桩 settings_volume_adj/settings_volume_step/meow_media_playctl/now_ms/logmsg。
