Complete architectural refactoring from simple MVC to Clean Architecture/DDD pattern: Domain Layer: - Add entities (Post, BaseEntity) with business logic - Add value objects (Title, Content, Slug) with validation - Add repository interfaces (PostRepository) - Add domain exceptions Application Layer: - Add use cases (CreatePost, GetPost, UpdatePost, DeletePost, ListPosts, PublishPost) - Add DTOs for data transfer - Add TransactionManager interface Infrastructure Layer: - Add SQLAlchemy models and async database connection - Add SQLAlchemyPostRepository implementation - Add Dishka DI container with providers - Add error handlers and middleware Presentation Layer: - Add FastAPI routes with Dishka integration - Add Pydantic schemas - Add dependency injection using FromDishka[T] Other Changes: - Remove old flat structure (api/, common/, core/, modules/) - Add hatchling build system for package scripts - Add blog CLI command - Update AGENTS.md with new architecture docs - All 48 tests passing, mypy clean, ruff clean
