Typed ORM with automatic migrations: Fitz vs SQLAlchemy + Alembic + Pydantic

Fitz is a typed ORM that simplifies database management by combining SQLAlchemy, Pydantic, and Alembic into one type with decorators. This results in 8x faster performance and 5x less memory usage compared to SQLAlchemy. To switch, maintain a single source of truth with Fitz instead of three separate sources.
