v1.3.2 — verbose logging to diagnose missing active=1b write

증상: chat_answer:status active 가 0b 그대로 → 데이터팩 login 메시지 안 뜸.
mq:load 는 정상 작동(0b 초기화 됨)인데 모드의 onPlayerJoin 이 1b 로 안 씀.

추가 로그:
  - ChatAnswerFabric.onInitialize: 진입/완료, event register 예외시 ERROR
  - ChatAnswerCore.onPlayerJoin: 진입 (player 이름 포함), 성공 시 INFO,
    실패 catch 를 LOG.debug → LOG.warn 으로 승격해 latest.log 에 보이게.

이 로그를 보고 다음 중 어디서 깨지는지 좁힐 수 있음:
  - "Fabric entrypoint onInitialize starting" 안 보임 → nested jar 미로드
  - "onInitialize starting" 보이고 "registered" 안 보임 → fabric-api ABI mismatch
  - "onPlayerJoin fired" 안 보임 → JOIN 이벤트 미발화
  - "active=1b set" 안 보이고 "failed" 만 보임 → command 실행 실패
