Validates the tags assigned to a workflow.

Checks for:
- Required tags: Tags that must be present.
- Forbidden tags: Tags that must not be present.

You can configure both sets of tags using multi-line lists, and optionally toggle case sensitivity for each list. If any required tags are missing, or any forbidden tags are found, the check fails.

The check uses the Workflow Metadata column, typically generated by the "Workflow Summary Extractor" node.
