Subject: [PATCH] New task
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

CI/CD로 배포 시작됐습니다.

**원인 및 수정 내용:**

**버그:** `solveCaptcha()`가 "TOO FREQUENT" 에러를 던지면 catch에서 **즉시 return**해서 재시도 루프를 탈출했음

**수정:**
- TOO FREQUENT 에러 감지 시 → **10초 대기 후 재시도** (최대 5회까지)
- 재시도 간 기본 딜레이: 2초 → **3초**
- 쿠폰 간 딜레이: 3초 → **5초** (연속 쿠폰 처리 시 WOS 서버 부하 감소)
