load_graph/stop_node/start_node each called notify() (push to all
clients) and then sent a direct response — the requesting client
got two identical messages, breaking test recv sequencing.
Use thread_local tl_requester to skip the requesting connection
in the push. notify() is called synchronously from the command,
so the thread_local is visible from the status_cb. Other clients
still receive the push; the requester gets only the direct response.
