nuxt/cli

AI Summary: Implement a `--extends` option for the Nuxt CLI (nuxi) to allow extending the CLI functionality from other projects, such as Docus, preventing the creation of separate CLIs and ensuring consistency and performance improvements across the Nuxt ecosystem.

AI Summary: The task is to modify the Nuxt CLI (nuxi) to support project-based typechecking using `vue-tsc -b --noEmit` instead of `vue-tsc --noEmit`. This involves changing the CLI's internal commands to incorporate the `-b` flag for building the project before typechecking, addressing an issue where the current implementation fails to correctly typecheck projects.

AI Summary: Investigate and resolve a size regression in the `create-nuxt` command within the Nuxt CLI (nuxi) project. The issue is likely related to the build process resulting in an unnecessarily large output.
