Function wait_for_socket 

pub fn wait_for_socket(
    socket: impl AsRef<Path>,
    timeout: Duration,
) -> Result<()>

Wait until a daemon is reachable at socket, polling at ~50ms. On Unix this checks for the AF_UNIX socket file; on Windows it connect-probes the named pipe (pipes don’t appear on the filesystem). Returns Ok(()) on success, error on timeout.
