fix: concluded discussions suppress turns and send single auto-reply

Two bugs in concluded discussion channel handling:

1. before_model_resolve did not check rec.discussion.concluded, so it
   still initialized the speaker list and ran turn management. Fixed by
   returning NO_REPLY early for concluded discussions (same as report mode).

2. message_received fired for all agent VM contexts, causing multiple
   "This discussion is closed" auto-replies per incoming message. Fixed
   with process-level dedup keyed on channelId:messageId (same pattern
   as agent_end runId dedup). Also fixed message_id extraction to look
   in metadata.conversation_info.message_id first.
