Merging this PR will trigger the
Release Helm Charts
workflow, which will:

1. Run helm package on the updated chart.
2. Merge the new package into index.yaml (preserving existing chart timestamps).
3. Publish the chart archive and updated index to the
   Nebari Helm Repository.

Note: This PR was opened automatically. Review the chart diff before merging.

To refresh it:

• New upstream release: push the release in the source repository, and this
  branch is force-updated automatically by the upstream sync workflow.
• Branch fell behind main (e.g., Chart.yaml conflict because a sibling
  sync PR merged first): comment /sync-rebase on this PR. A maintainer-gated
  workflow rebases the branch onto current main, resolving the
  version / appVersion clash automatically.

Smoke-test artifact from exercising the template's release pipeline (nebari-dev/software-pack-template#28). my-pack is a placeholder example chart, not something we publish - closing without merging. A dedicated, safe test fixture now lives at nebari-dev/pack-testbed.
