319fd18258 feat(stats): #337 봇 UA 필터 + IP 레이트리밋 
- BotDetector 유틸 (Pattern.CASE_INSENSITIVE: bot|crawler|spider|slurp|scrap|fetch|monitor|preview|lighthouse)
- RateLimitService: Redis SET NX EX(60s) 패턴으로 같은 IP 윈도우 차단
  - Bucket4j 대신 spring-data-redis 기존 의존성 재사용 (간결)
  - Redis 다운 시 fail-open (사용자 경험 우선)
- StatsController.recordVisit: HttpServletRequest 받아 UA + X-Forwarded-For 우선 IP
  - 봇/리밋 초과 → 200 + counted:false (사용자 페이지 로드 지장 X)
  - 통과 → 200 + counted:true → statsService.recordVisit()
- application.yml: app.rate-limit.visit-window-seconds (env VISIT_WINDOW_SECONDS) 기본 60
- dev 검증: 봇 UA → counted=false, Mozilla → true, 즉시 재호출 → false

c16add08c3 Migrate to MyBatis with proper Controller→Service→Mapper layering 
- Add MyBatis Spring Boot Starter with XML mappers and domain classes
- Create 9 mapper interfaces + XML: Restaurant, Video, Channel, Review,
  User, Stats, DaemonConfig, Search, Vector
- Create 10 domain classes with Lombok: Restaurant, VideoSummary,
  VideoDetail, VideoRestaurantLink, Channel, Review, UserInfo,
  DaemonConfig, SiteVisitStats, VectorSearchResult
- Create 7 new service classes: RestaurantService, VideoService,
  ChannelService, ReviewService, UserService, StatsService,
  DaemonConfigService
- Refactor all controllers to be thin (HTTP + auth only), delegating
  business logic to services
- Refactor SearchService, PipelineService, DaemonScheduler, AuthService,
  YouTubeService to use mappers/services instead of JDBC/repositories
- Add Jackson SNAKE_CASE property naming for consistent API responses
- Add ClobTypeHandler for Oracle CLOB→String in MyBatis
- Add IdGenerator utility for centralized UUID generation
- Delete old repository/ package (6 files), JdbcConfig, LowerCaseKeyAdvice
- VectorService retains JDBC for Oracle VECTOR type support
