Introduce CAC

[Barbapapazes]

Describe the feature

Hello,

In order to easily add new command and understand how the CLI works (because there is more and more feature), I think that we could use a tool like CAC, https://github.com/cacjs/cac, to achieve this.

Currently, there is no -h flag and there is many more flag to come.

#104 with a --prevenance
#105 with a --publish
nuxt/nuxt#20675 with a flag to create a PR (where we could personalize changelog header)

Additional information

• Would you be willing to help implement this feature?

Hey :) Our CLI is powered by unjs/citty. Check src/cli.ts and src/command. For now args are not documented (because of backward compatibility) but once we add meta, --help will show them..

Sorry to ask but I dit not find any unjs/citty in the repo? 🤷‍♂️

Ok, I tried a bit citty and when it will be available for changelogen, it would be awesome! Can't wait!
