ipc.Client serialises every call on one mutex, and mavweb routed 28
handlers plus /api/chat through the shared client. A turn is bounded
only by phraser.timeout, 60s in deploy, so a page load behind one could
wait that long.
/models already had its own connection for this reason. Chat gets the
third one. A failed dial logs and falls back to the shared client, which
is how it behaved before.
/api/ptt needs nothing here: it proxies to the voice port and never
touches this client.
A connection pool inside ipc.Client is the general form and stays
unbuilt until a second module is measured queueing.
