Fixes#77656.
Summary:
- Carry chat turn-source metadata through approved async host=node replays.
- Bind trusted backend replay to node, command, session, agent, and chat target metadata instead of transient WebSocket connection ids.
- Cover Telegram and WeCom-style reconnect replay plus denial cases with gateway, websocket, and agent tests.
- Carry the current-main CLI help assertion fix needed to clear exact-head CI after the rebase.
