feat(resource): allow canonical resources to satisfy regular dependencies

The satisfied_by method in ResourceRef now allows canonical library types
to satisfy regular library dependencies of the same name, and canonical
library resource types to satisfy regular library resource dependencies.
This enables more flexible resource resolution while maintaining type
safety.
