Three agents in flight in worktrees:
A — versionnegotiation testcase + configurable initial-version writer
B — qlog observer infrastructure (QlogObserver interface in :quic,
JSON-NDJSON writer in :quic-interop, hooks at packet/key/recovery
sites, reads $QLOGDIR the runner already sets)
C — multiplexing channel-saturation fix (consume server's peer uni
streams in Http3GetClient — RFC 9114 §6.2 says clients MUST
process incoming control + QPACK streams)
Plan doc now also captures the latest test matrix (pre-acfe815e1
multi-ALPN-offer fix) and the predictions for the next run.
