    # This workflow is triggered only on pushes to the `main`, `*.staging` or 'migrate' branches.
    # For `*.staging` and `migrate` it specifically checks if the commit message starts with `::migrate::`,
    # indicating a migration-related change.
    #
    # Example usage:
    #   Execute a commit with a migration flag using:
    #   git commit --allow-empty -m "::migrate::test description"
    # Note:
    #   This setup is a temporary measure. The intention is to transition to a fully automated publish and release process via GitHub Actions in the future.
