class Endpoint

Abstracts the differences between Helm chart sources.

Traditional Helm repos require helm repo add before charts can be referenced, and charts are addressed as "repo-name/chart-name".

OCI registries need no repo add step, and charts are addressed as the full OCI URI: "oci://host/path/chart-name".
