Adds a new virtual repo type that merges indexes from multiple member remotes
of the same package type. Currently supports helm (index.yaml merge with URL
rewriting). Member fetches run in parallel; merged index is Redis-cached at
min(mutable_ttl) across members.
examples/single-file/remotes.yaml — original monolithic config
examples/conf.d-method/ — one yaml per remote (alpine, github, pypi)
docker-compose updated to mount from examples/single-file/.
