feat: implement repository architecture with smart caching

- Add base repository interfaces and abstract classes
  - Implement separated read/write repositories for Domain and Username models
  - Add intelligent query caching with automatic invalidation
  - Include cache management service and CLI commands
  - Add comprehensive configuration for cache TTL and monitoring
  - Enhance performance through optimized data access patterns
