📚 Description

this updates us to vitest v4 and drops support for previous versions of vitest.

there's still an issue with starting vitest programmatically (in the nuxt devtools) but it's unclear to me if this is a nuxt/test-utils bug or a vitest one

There is a problem with runtime config:

  runtimeConfig: {
    public: {
      whatever: {
        hello: 'world',
      },
    },
  },

  it('renders', () => {
    const config = useRuntimeConfig()
    console.log('public', config.public)
  })

public {}
