✨ DDD - Introduce DDD into clean architecture

[christoment]

The current Clean Architecture framework relies on an anemic domain model, which simplifies initial development but increasingly hampers our ability to handle the complex interactions and business logic inherent in our domain. By incorporating Domain-Driven Design (DDD), projects with non-trivial logic can better accommodate complex workflows and business rule integrations without compromising maintainability or scalability.

We would like to default to using DDD in the template and provide a good example of building applications in that manner.
