Expose matching route meta in event handler

Describe the feature

Hello! I'm not sure this is a bug, but definitely something I need. I'm using defineRouteMeta to add documentation around some endpoints. Those endpoint are being protected using an ApiKey, AND a scope.
I do need a way to access the matched route meta from a middleware in order to check the matched route scope expectations against scope allowed by the api key. If I do have access to the latest, I'm struggling to find a way to read route metas from the middleware itself.
My proposal is simply to add event.meta.
Thoughts?

Start by tracing how defineRouteMeta data is attached to matched routes and how middleware receives the event. Check whether the matched route metadata is already available at the event-handler entry point. Done means middleware can read the matched route's metadata through event.meta, with coverage for checking endpoint scope expectations against an API key.
