- Add tier_capture param to _run_agent_pipeline; append tier after determination
- Capture actual_tier in run_agent_task from tier_capture list
- Log tier in replied-in line: [agent] replied in Xs tier=Y
- Remove reply_text[:200] truncation (was breaking benchmark keyword matching)
- Update parse_run_block regex to match new log format; llm/send fields now None
