Android 대응 이벤트명 (동일)

• action_run_start/complete/abandon — 러닝 블랙박스 해소
• view_countdown, click_cancel_countdown — 러닝 직전 이탈 측정
• view_course_complete_result — 코스 완성 후 분기 측정
• click_run_from_detail — 코스 발견→러닝 전환 측정
• action_login_success/fail — 로그인 전환율, 장애 감지

영향 범위

• 기존 이벤트 로깅 코드 변경 없음 (신규 추가만)
• GAManager에 .custom case 추가 (기존 .screen, .button, .share 호환 유지)
• 런타임 영향: Firebase logEvent 호출 추가 (경량, 비동기)

Test Plan

• 빌드 환경 세팅 후 빌드 성공 확인 (현재 빌드 파일 미전달)
• Firebase DebugView에서 이벤트 발화 확인
• Android와 동일 이벤트명인지 크로스 체크
• BigQuery에서 platform별 퍼널 쿼리 검증
