Pull request overview

Updates the GitHub Actions workflow responsible for testing device roles so it also runs when deploy_ioc per-role var files change, ensuring CI coverage for role-affecting configuration updates.

Changes:

• Renames the workflow and the change-detection step for clearer intent.
• Extends the pull_request path filters to include roles/deploy_ioc/vars/**.
• Updates role detection logic to derive impacted device roles from either roles/device_roles/** changes or roles/deploy_ioc/vars/<role>.yml changes.

• The deploy_ioc/vars case assumes the filename is always the 4th path segment (a[4]). Since the workflow trigger includes roles/deploy_ioc/vars/** (which can include nested subdirectories), any deeper path (e.g., roles/deploy_ioc/vars/subdir/foo.yml) would extract the wrong role name and silently skip testing. Consider extracting the basename from the last path segment (and then stripping the .yml suffix) to make this robust to nesting.
