New task
**완벽하게 동작해요!**
```json
{"found": 4, "added": []}
```
- **found: 4** → Wiki에서 코드 4개 정상 파싱됨
- **added: []** → 이미 DB에 있는 코드들 (전부 중복)
Wiki 코드 4개 (`HappyMayDay`, `GW2026JP`, `OFFICIALSTORE`, `gogoWOS`)가 이미 DB에 등록되어 있어서 스킵된 거예요.
---
## 정리된 동작

A[매 정시 크론] --> B[whiteoutsurvival.wiki 페이지 다운로드]
B --> C[span.code 파싱 - 정규식]
C --> D{DB 중복 체크}
D -->|기존 코드| E[스킵]
D -->|신규 코드| F[addCoupon 호출]
F --> G[전체 유저 자동 지급]
F --> H[Discord Webhook 알림]
```
이제 **매 정시마다 자동으로 Wiki를 확인**하고, 새 쿠폰이 추가되면 자동으로 전체 연맹원에게 지급돼요. Reddit OAuth 같은 복잡한 설정도 필요 없어요!
