Layer 1 root cause 진단을 위해 classify_worker.py:595 의 exception logging
을 lazy formatting + exc_info=True 로 강화. f-string 1줄 → 5줄 block.
- type=%s: exception class name (TimeoutError/JSONDecodeError/ValueError/etc.)
- repr=%r: full exception state
- exc_info=True: traceback 까지 capture (wrapper 정확 지점 추적)

본 PR scope = Diagnose only. Layer 1 specific fix (H1/H2/H3/H4) + Layer 2
escalate path ai_event_kind fallback set 은 별 PR queue.
