MeowOS-SDK/sdk/test_sdk_input_keys.c

/*
 * test_sdk_input_keys.c — M2.55 宿主验证：SDK 输入层接管系统按键语义（App 前台也生效）。
 *
 * 覆盖（直接调输入层语义函数，等效"模拟按键事件"）：
 *   K1 音量 +/step：audio.volume 迈一步（volume_step 约束），settings.conf 落到值改变；
 *   K2 音量 ± clamp：volume_max 软上限、0 下限、硬上限 100；到限不再写；
 *   K3 保留其它键：改 audio.volume 不整文件 O_TRUNC（display.brightness/注释保留）；
 *   K4 媒体键本地回调：注册 playctl 回调后，sys_key(上一曲/下一曲/播放暂停) → 回调 cmd 正确
 *      （播放/暂停恒发 toggle(6)，SDK 不再本地判 state——走自有 IPC 线程的源不经 SDK meta
 *      上报，本地 state 恒 0 会恒发「播放」致播放中按键无效；源侧按当前态翻转）；
 *   K5 媒体键 IPC 兜底：未注册回调（g_cb==NULL）→ 走 IPC 发 launcher（无 socket → 静默不崩）。
 *
 * 编译（宿主 gcc，仅链 vol/media 两个 TU；无需 meow_ui 其它子系统）：
 *   gcc -Wall -Wextra -pthread -o test_sdk_input_keys test_sdk_input_keys.c \
 *       meow_ui_vol.c meow_ui_media.c -I. -I../meow_launcherd
