chore: convert to component library
- update dependencies
- remove default "app" page/index (all "examples" are handled through ladle – everything else will be part of the consuming projects)
- remove parcel (use vite instead, since it's already a dependency of ladle – I'd rather have one bundler for everything instead of two different bundlers. we can still use parcel in the actual website repo/project)
- configure vite and npm for package publishing to gitlab registry
- use npm instead of yarn v1
