从手机如何调用Claude code？示例只给了 copilot

`npx @rebornix/stdio-to-ws "copilot --acp" --port 3000 --persist --grace-period -1` 这样开启的是co-pilot.

我尝试了`npx @rebornix/stdio-to-ws "npx @zed-industries/claude-code-acp@latest" --port 3000 --persist --grace-period -1`，但这样连接时报错：

```
[stdio-to-ws] WebSocket server listening on port 3000 (persistence enabled, grace period: infinite)

}
[stdio-to-ws] Cleaning up client 1d8b9328-f6a1-4416-a262-a9c8e525925b
```

直接跑 `npx @zed-industries/claude-code-acp@latest` 没有输出，也看不出什么帮助信息。

Start by reproducing the documented Copilot command and the reported Claude ACP command, then inspect the stdio-to-ws invocation and its spawn npx ENOENT error. Done means the mobile usage instructions explain a working Claude Code connection or clearly document the required environment and limitation; no project files or tests are named in the issue.
