  * QUIC: implement PTO (Probe Timeout, RFC 9002 §6.2) — retransmit

    the oldest unacked packet with exponential back-off when the peer

    has not acknowledged tail packets, fixing the "tail loss" deadlock

    where both sides wait indefinitely after the last few UDP datagrams

    are lost

  * QUIC: pumpNetwork() now calls checkLossAndRetransmit() so that

    callers waiting for responses (e.g. parity store_stripe Phase 2)

    trigger retransmission of lost packets

  * QUIC: fix sendStreamData(vector) silently losing data on congestion

    control stall — now retries in a loop with pumpIncoming() between

    attempts until all data (including FIN) is delivered

  * QUIC: only mark stream send_fin when all data was actually sent on

    the wire, preventing incorrect state when CC breaks the send loop
