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
