Detailed Description

Declares a dependency between datasets using stable dataset codes.

When a dataset is injected into the system, all its dependencies must be satisfied first. Dependencies are resolved by code at injection time, allowing for loose coupling between datasets.

This enables building a dependency graph where, for example, an "iso.countries" dataset can declare that it depends on "assets.country_flags" for visual display.

The dependency_code is intentionally NOT a foreign key - it's resolved at injection time. This allows:

• Declaring dependencies on datasets that may not exist yet
• Referencing datasets that live in external systems
• Loose coupling with validation at injection time
