yxxhero c5eebc24bd fix: helmfile deps broken for OCI charts with underscores in path (#2648) 
fix: helmfile deps broken for OCI charts with underscores in path (#954)

For OCI charts with multi-segment paths (e.g., myrepo/path_with_underscores/example),
helmfile was putting the full path as the dependency name in the generated Chart.yaml.
Helm then reconstructed the OCI reference using this name, and underscores in the
path caused issues with helm's OCI reference handling during dependency update.

Fix: move the chart path prefix into the repository URL and use only the chart
basename as the dependency name, matching Helm's recommended Chart.yaml format
for OCI dependencies:

  # Before (broken):
  dependencies:
  - name: path_with_underscores/example
    repository: oci://harbor.custom.com

  # After (fixed):
  dependencies:
  - name: example
    repository: oci://harbor.custom.com/path_with_underscores

The resulting OCI reference is identical, but the dependency name is now clean.

Includes backward-compatibility fallback for old lock files that used the full
path as the dependency name.
