Pull request overview

Updates the repository’s GitHub Actions configuration so public repositories use the “public” reusable workflows by default, while still providing a separate workflow to exercise the private-workflow variants.

Changes:

• Switches ci.yml to call the *-public.yml reusable workflows by default.
• Adds a new test-private-workflows.yml workflow to validate the private reusable workflows.
• Adds an inline version comment to the Release Please action pin in release.yml.

• build-plugin-zip runs on both push and pull_request, but artifact-name is built from github.event.pull_request.*. On push events those fields are not present, producing an odd/empty artifact name suffix and making artifacts harder to identify. Consider using a conditional expression that falls back to ${{ github.sha }} (or ${{ github.run_id }}) when not running on a PR.

    with:
      php-version: '8.2'
      artifact-name: plugin-skeleton-d-pr${{ github.event.pull_request.number }}-${{ github.event.pull_request.head.sha }}
