MeowOS-SDK/sdk/test_meow_ui_select.c

/* test_meow_ui_select.c — 宿主验证枚举/预设选择器（meow_select）：
 * T1 打开→点选项→单选高亮（primaryContainer）+ 选中 + 关闭即回调（on_change(idx)）+ 返回值。
 * T2 取消：点面板外（遮罩）→ 返回 -1，不调 on_change。
 * T3 meow_select_show 一次性：返回选中下标。
 *
 * 阻塞式模态用后台线程驱动（同 test_ime_fix 范式），主线程经 meow_input_inject 喂触摸。
 * 编译（宿主 gcc）：
 *   gcc -o test_meow_ui_select test_meow_ui_select.c test_host_stub.c \
