pub fn serve(socket_path: &str)Expand description
Main daemon loop: spawn bash, accept connections, proxy commands.
Called by reef daemon _serve (internal, not user-facing).
§Panics
Panics if bash.stdin or bash.stdout cannot be taken after spawning
with Stdio::piped(). This is infallible in practice — take() only
returns None if called twice, and we call it exactly once.
