sdk/： - 同步 meow_ui_widget/input/gfx/lazygrid/audio/media/img 等源码与头 （SDK 默认列表/容器控件默认 MD3 — meow_list_set_container 可回退； 全局 App 内底部上滑回桌面 — meow_ui_input_is_home_swipe 系统保留手势； LazyGrid/LazyColumn/LazyRow MD3 化；叠加让位自抑改 app_id 判定； DSD 音频格式等） - 新增独立模块源码 meow_img_color / meow_lyric / meow_lyric_view 及对应宿主 test_*.c - 保留公开仓自包含适配：vendored meow_font.c/meow_font.h/meow_notif.h 不动； build_sdk.sh 自包含版本不动；meow_ui_gfx.c 仅改 meow_font.h include 路径； meow_ui_internal.h 去除 FreeType 内部声明 - meow_ipc.h 同步到主仓 launcher 版本（含 AUDIO_FMT_DOP/媒体歌词/蓝牙输出协议） - 不含 FreeType 矢量字 meow_ft_*（需 freetype vendor，公开仓以位图 meow_font 自包含）；不含 mipsel 二进制 / .o / .a / 固件 / 密钥 / devdocs examples/hello/： - 新增 ui/demo/sdk2/sdk2.c；build_hello.sh 纳入该文件（保持自包含） docs / README / .gitignore： - docs/MEOW_APP_SDK.md 补 §12.5（默认 MD3 容器 + 底部上滑回桌面 + 两个新 API） - README 能力清单补「默认 MD3 容器」与「底部上滑回桌面」 - .gitignore 补新增宿主测试二进制 验证：sdk/meow_ui.a 与 examples/hello/hello 交叉编译均 0 warning；工作区无生成物。

/* meow_ui_media.c — App 侧媒体会话封装（SDK 公共件；见 meow_ui_media.h）。
|

*
|
||
* 传输：AF_UNIX SOCK_STREAM 到 MEOW_IPC_SOCK（缺省 /usr/data/meow_ipc.sock）。后台线程持有
|
||
* 持久连接：HELLO(app_id, MF_PLAYBACK) 注册为媒体源 + poll 读 launcher 下发 MSG_PLAYCTL（经
|
||
* 该连接 fd 回发，见 launcher meow_media.c send_playctl）。meow_ui_media_meta() 在调用线程
|
||
* 直接经同一连接发 MSG_META（全双工：写 META、读 PLAYCTL 互不干扰）。
|
||
*
|
||
* 连接生命周期（best-effort）：懒连（首次 meta / 注册回调时 connect+HELLO+ACK）；
|
||
* 断线（读失败/写失败）→ close+置 -1，下次 meta 重连；launcher 不在 → connect 失败 → 静默。
|
||
* 线程安全：g_fd 读写经互斥；后台线程只在 poll/读失败时改 fd，meta 线程只在 connect 时改 fd。
