Adds :quic-interop, a JVM-only module at quic/interop/ that implements the quic-interop-runner Docker contract so we can drive matrix tests against aioquic / quiche / picoquic / msquic / ngtcp2 / etc. as a bug-finding harness. Phase 0 supports only the `handshake` testcase; everything else returns 127 so the runner skips rather than fails. SSLKEYLOGFILE / QLOGDIR plumbing is deferred to Phase 1. https://claude.ai/code/session_01HcvfQq1ttPV9PkRoJb4nyT
