Subject: [PATCH] feat: allow empty base_path for distributions

This enables Docker registry mirror compatibility by allowing
pull-through distributions to serve at the root path (empty base_path).

When base_path is empty, the distribution matches all incoming paths,
making it work as a transparent Docker Hub mirror.
