A standalone, domain-agnostic pub/sub seam: an EventBus that owns its subscriber registry and streams Event values from producers to listeners in process. Boundary-crossing (Celery/DB/workers) is left to subscribers, keeping the bus single-responsibility. Includes the immutable Event value object and full unit coverage.
