fn run_desktop_proxy() -> Result<(), String>Expand description
Proxy MCP stdio ↔ the Webizen Desktop GUI’s TCP MCP server (127.0.0.1:4245). An external MCP client that speaks stdio (e.g. an editor agent) can drive the desktop app’s tool surface through this bridge: each stdin JSON-RPC line is forwarded to the desktop server and its reply written to stdout.
