- Add UserRepository and LinkedAccountRepository protocols to protocols.py
- Add UserEntry and LinkedAccountEntry DTOs for service layer decoupling
- Implement PostgresUserRepository and PostgresLinkedAccountRepository
- Refactor UserService to use constructor-injected repositories
- Add get_user_service factory and UserServiceDep to API deps
- Update auth.py and users.py endpoints to use UserServiceDep
- Rewrite tests to use FastAPI dependency overrides (no monkey patching)
This follows the established repository pattern used by DeckService and
CollectionService, enabling future offline fork support.

Implemented with Repository Protocol pattern for offline fork support:
- CollectionService with PostgresCollectionRepository
- DeckService with PostgresDeckRepository
- DeckValidator with DeckConfig + CardService injection
- Starter deck definitions (5 types: grass, fire, water, psychic, lightning)
- Pydantic schemas for collection and deck APIs
- Unit tests for DeckValidator (32 tests passing)
Architecture follows pure dependency injection - no service locator patterns.
Added CLAUDE.md documenting DI requirements and patterns.
