    unetmsg: only send publish notifications for remote publisher changes
    
    handle_publish() notifies local subscribers about publisher state
    changes. The publish/subscribe handler in network_socket_handle_request()
    was calling it for both remote publish and subscribe changes, but
    subscriber changes are not relevant to local subscribers.
    
    Guard the handle_publish() calls with a msgtype == "publish" check,
    matching the local client paths in unetmsgd-client.uc which already
    have this guard.
