feat(lib)!: disable skipLibCheck in library tsconfig, closes #5

BREAKING CHANGE:
This change requires libraries extending `tsconfig.lib.json` to be
type-checked against their dependencies as well as the `.d.ts`
files in their own projects. So it might introduce new type errors.

It bumps the Vue.js version requirement to `^3.4.0`, as the Vue.js core
can only be correctly type-checked in `--isolatedModules` mode after
version 3.4 (following the removal of `const enum` usage).

It might also increase the compilation time of the library projects.
