fix(net): bound every request with a timeout

A server that stops answering without closing the socket left a running
sync waiting forever. Requests now fail with TimeoutException after 30 s
(10 s for the handshake, both configurable in ConnectAsync) and the
connection is marked dead so the app reconnects. See ADR 0034.
