Describe the feature

Hello!

I'm currently working on implementing devtools for Nuxt UI (PR: #2196). As part of this, I need to inject a page within the user's app that allows our devtools to render components based on the user's Nuxt UI configuration.

The challenge I'm encountering is that I could not find a way to inject this page without inheriting from the user's app.vue (using extendPages) , which could cause unintended side effects.

To address this, I thought we could introduce a way to inject pages without inheriting from app.vue, similar to what’s done in for the test utils, by rendering the nuxt page directly if it matches a specific condition.
