Agent B's QlogWriter previously lived only in :quic's jvmTest scope,
hooked into the standalone InteropRunner. Brings it into :quic-interop
proper:
- QlogWriter.kt + QlogWriterTest.kt copied into :quic-interop with
package com.vitorpamplona.quic.interop.runner.
- Jackson dep added to :quic-interop's build.gradle.kts.
- InteropClient reads $QLOGDIR (the runner sets it inside the
container per docker-compose.yml). When set, opens a QlogWriter
at <QLOGDIR>/client.sqlog, passes as QuicConnection.qlogObserver,
closes on every exit path (handshake_failed / udp_failed /
transfer_timeout / ok).
- QUIC_INTEROP_DEBUG=1 now prints qlogdir alongside the other env
fields.
Net effect: any future runner-driven test failure dumps a structured
qlog file the user can drag straight into qvis (qvis.quictools.info)
to see frame-by-frame what the client decided to do. The retry test
failure on aioquic + picoquic that we still need to debug now produces
a usable artifact.
NOTE: the QlogWriter copy in :quic's jvmTest stays in place as the
helper for the standalone InteropRunner main(). Slight duplication;
acceptable while :quic-interop is its own module.
