Output directory is recursively removed

[romhml]

I had a small surprise while exploring ways to generate types for a Nuxt Module, the directory specified in the --outputDir is recursively removed.

Reproduction: https://stackblitz.com/edit/stackblitz-starters-kjvwap

Running pnpm nuxt-component-meta playground --outputDir ../ will remove the parent folder. While this might not be the brightest idea, I think the punishment for it is a bit hard.

Ideally, the cli should only remove its files from the --outputDir directory.
