    The Backstage Events system provides a publish-subscribe mechanism for
    broadcasting and consuming events within a Backstage instance. It enables
    plugins to emit events when significant actions occur (such as catalog

    and allows other plugins or external systems to subscribe to those events
    via HTTP webhooks or the internal event bus.
