Step 9: 고급 이벤트 처리 시스템 구현
주요 기능: - Kafka 이벤트 컨슈머 및 프로듀서 통합 - 지수 백오프 재시도 메커니즘 구현 - Dead Letter Queue (DLQ) 설정 - 이벤트 스키마 레지스트리 (Pydantic v2 호환) - Console 서비스에 이벤트 관리 API 추가 - 실시간 이벤트 통계 및 모니터링 - 엔드-투-엔드 테스트 스크립트 구현된 이벤트 타입: - USER_CREATED, USER_UPDATED, USER_DELETED - OAUTH_APP_CREATED, OAUTH_TOKEN_ISSUED - IMAGE_UPLOADED, IMAGE_PROCESSED 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
