- Add sdk_conversation_id column to track SDK conversation separately from user session_id
- Queue processor looks up SDK conversation ID for resume instead of passing user session_id
- session_id "new" stores NULL initially, gets set from SDK on completion
- Custom session_ids are preserved (not overwritten by SDK)
- Worker catches SDK process exit error after messages are collected
