chore: migrate to nuxt 5 beta (nuxt-nightly@5x) and clean up dependencies

- Replace pkg.pr.new nuxt/kit/schema nightlies with official nuxt-nightly@5x
- Add nuxt/kit/schema overrides in pnpm-workspace.yaml for consistent resolution
- Update examples/nuxt to use npm:nuxt-nightly@5x
- Remove stale vue-router overrides (no longer needed with nuxt 5)
- Delete pnpm-lock.yaml for clean dependency resolution
