feat(sdk): meow_config_* App配置读写API(agent-158)
- 6 API: meow_config_dir/set/get/int/bool/remove; 落 TF MeowData/<pkg>/data/<key>.cfg(env MEOW_DATA_DIR, 回退/tmp/meowcfg_<pid>) - 与系统设置 meow_settings_*(板载settings.conf) 区分; key清洗[A-Za-z0-9._-]→_ 防路径穿越; 值上限4096; 降级不崩(pthread_once/mutex) - MEOW_CFG_* 错误码(避开 meow_ipc.h 枚举命名空间, 防宏展开冲突); 数值与 MEOWOS_API/meow_settings.h 同值 - meow_ui.a=92e61fb8(新增config成员) hello=5e31d919不变(0回归, 静态链未拉入新成员); build_sdk 0warning; 宿主test_meow_ui_config ALL PASS - 未重链launcher(launcher未用config); 遗留真机验证MEOW_DATA_DIR落盘/无卡降级

/*
|
||||
* test_meow_ui_config.c — meow_config_* 宿主单测（2026-08-30）。
|
||||
*
|
||||
* 编译（宿主，config 为纯 libc，无需 SDK 其它对象）：
|
||||
* gcc -Wall -Wextra test_meow_ui_config.c meow_ui_config.c -o test_meow_ui_config -lpthread
|
||||
*
|
||||
* 两种模式（meow_config_dir 经 pthread_once 缓存，目录只在首次调用确定，故分两次跑）：
|
||||
* ./test_meow_ui_config env → 设 MEOW_DATA_DIR=<mkdtemp>，验证持久目录读写
|
||||
* ./test_meow_ui_config tmp → unsetenv MEOW_DATA_DIR，验证 /tmp/meowcfg_<pid> 回退
|
||||
*
|
||||
* 任一断言失败 → 打印 FAIL 并以非零退出码结束。
