Stable desktop installers are public release assets, including the macOS direct download through the website release proxy.

The desktop app owns local state, agent hooks, device setup, firmware flashing, and the local runtime path from software state to the physical signal light.

Agent hooks report work state into the desktop runtime; the runtime maps green idle, yellow thinking or running, and red waiting states to the ESP32 firmware.

Use green idle when the agent is ready, yellow thinking or running while work is active, and red waiting when user attention is needed.

稳定桌面安装包是公开 release assets，包括通过官网 release proxy 提供的 macOS 直接下载。

桌面 app 负责本地状态、agent hooks、设备设置、固件刷写，以及从软件状态到物理信号灯的本地 runtime 路径。

Agent hooks 把工作状态报告给桌面 runtime；runtime 把绿色空闲、黄色思考或运行、红色等待状态映射到 ESP32 固件。

Agent 就绪时使用绿色空闲，工作进行中使用黄色思考或运行，需要用户处理时使用红色等待。
