Hooks should be configurable directly in the config, so they are more consistent while used within bundlers and frameworks

### Describe the problem

For example Nuxt 3 + Vite imports works in a magic way and Stylify imported in `stylify.config.mjs` is not the same as Stylify imported during build, therefore hooks defined in `stylify.config.mjs` doesn't work ¯\_(ツ)_/¯.
