What's the documentation problem or suggestion?

Problem

docs/ArchitectureLearningJourney.md appears to describe an older For You feed flow.

The document references GetUserNewsResourcesUseCase, but that class no longer exists in the current codebase. The current implementation uses:

• ForYouViewModel.feedState
• UserNewsResourceRepository.observeAllForFollowedTopics
• CompositeUserNewsResourceRepository, which combines NewsRepository data with UserDataRepository data

The domain-layer example also uses GetUserNewsResourcesUseCase, so readers following the architecture learning journey may search for a class that is no longer present.

Suggested solution

Update docs/ArchitectureLearningJourney.md so it matches the current implementation:

• Replace the stale GetUserNewsResourcesUseCase references with UserNewsResourceRepository / CompositeUserNewsResourceRepository
• Point readers to ForYouViewModel.feedState for the For You feed flow
• Use GetFollowableTopicsUseCase as the current domain-layer example

I have opened a small documentation PR for this change.
