DoQWriter previously stored only the QUIC stream, so plugins reading
TLS state via dns.ConnectionStater (e.g. for SNI-based routing or
auditing) could not see anything for DoQ connections, even
though the underlying QUIC connection carries a full tls.ConnectionState.
This change adds a *quic.Conn reference to DoQWriter and wires it in serveQUICStream.
It implements dns.ConnectionStater on *DoQWriter, returning the TLS
state from the underlying QUIC connection (mirrors the DoT behavior
that miekg/dns already provides for *tls.Conn)
Forwards ConnectionState through request.ScrubWriter, which wraps
every response writer before the plugin chain runs; the embedded
dns.ResponseWriter interface does not promote ConnectionState (it
belongs to a separate interface), so without this plugins would
still see nil for both DoQ and DoT
