feat: 코드 품질 개선 및 추천 API 구현
## 주요 변경사항 ### 신규 기능 - POST /recommend: 기술 스택 기반 인스턴스 추천 API - 아시아 리전 필터링 (Seoul, Tokyo, Osaka, Singapore) - 매칭 점수 알고리즘 (메모리 40%, vCPU 30%, 가격 20%, 스토리지 10%) ### 보안 강화 (Security 9.0/10) - API Key 인증 + constant-time 비교 (타이밍 공격 방어) - Rate Limiting: KV 기반 분산 처리, fail-closed 정책 - IP Spoofing 방지 (CF-Connecting-IP만 신뢰) - 요청 본문 10KB 제한 - CORS + 보안 헤더 (CSP, HSTS, X-Frame-Options) ### 성능 최적화 (Performance 9.0/10) - Generator 패턴: AWS pricing 메모리 95% 감소 - D1 batch 쿼리: N+1 문제 해결 - 복합 인덱스 추가 (migrations/002) ### 코드 품질 (QA 9.0/10) - 127개 테스트 (vitest) - 구조화된 로깅 (민감정보 마스킹) - 상수 중앙화 (constants.ts) - 입력 검증 유틸리티 (utils/validation.ts) ### Vultr 연동 수정 - relay 서버 헤더: Authorization: Bearer → X-API-Key Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
