Isaac 5962a563e4 feat: tgcalls CLI test tool with group SFU, video, and adaptation
Squashed buildout of the tgcalls testbench:

- CLI test tool with --mode p2p/reflector/group/group-churn,
  cross-version interop (--version, --version2), and quiet/summary output
- Linux toolchain + Docker multi-stage build, AWS Fargate mass test harness,
  local parallel mass test harness with signaling loss simulation
- SCTP writable gate, retransmission timer tuning, role-based handshake
- InstanceV2CompatImpl (PeerConnection backend with V2Impl signaling) and
  SignalingTranslator for v14.0.0 interop
- In-process Go/Pion SFU (ICE+DTLS+SRTP+SCTP per participant) with audio
  RTP forwarding, ActiveAudio/VideoSsrcs data channel broadcast, RTCP
  feedback path, and CGo c-archive integration
- GroupInstanceReferenceImpl (PeerConnection group-call) and mixed-impl
  group mode (--reference-participants), with SDP munging for simulcast
- H264 simulcast group video (FakeVideoTrackSource pattern generator,
  FakeVideoSink frame counting, --video flag, two-pass channel setup,
  reactive video setup from ActiveVideoSsrcs)
- Group churn stress mode (--mode group-churn, --churn-cycles)
- SFU stream-quality adaptation: BandwidthEstimator, LayerSelector
  state machine, RtxRingBuffer, simulcast SSRC rewrite
- Transport-cc feedback generation, NetworkSimulator (delay/jitter/loss/
  token-bucket bandwidth), --network-scenario step-down-up
- CLAUDE.md updates throughout
