Retry a stream we cannot read, and cover the framer reset on attach

A framing or codec error tears the link down rather than the session, so
the loop retries it on a fresh socket with a fresh framer — which is what
a desynced stream needs. Removing that reset failed nothing before; the
reconnect test now leaves half a PDU on the dying link, and does.

`disconnected` counts failed links rather than outages, which the README
now says, and the transport wires its socket as it is built.
