Move testcontainers to optional dependency and create feature flag for database integration tests. Tests without the feature use a dummy pool and skip database operations.
All external services (database, Discord/GitHub OAuth, S3) can now be individually disabled by omitting their environment variables. The server gracefully degrades functionality when services are unavailable. Partial configuration of any service group triggers a clear error at startup.
- Database: Falls back to dummy pool when DATABASE_URL is unset
- OAuth: Providers only registered when credentials are complete
- S3: Image storage disabled when credentials are missing
- Health checks reflect actual configuration state
Organize recipes into dedicated Justfiles for pacman, server, and web components. Root Justfile now serves as a thin facade with common aliases pointing to submodule recipes.
