Package lazydeps records application dependency initialization and the dependency graph between services.
Applications receive a *Scope from lazyapp.Config.Dependencies and initialize shared services with Service. Service returns a typed Ref; calling Ref.Use inside another service initializer records that dependency edge and returns the wrapped service value.
