fix(docs): resolve @robonen/* workspace imports from source

The docs build pulls composables (via demos) and doc sections into its bundle, which transitively import workspace packages like @robonen/platform/multi. Aliasing each @robonen/* package to its src means the build no longer requires every package's dist to be built first, fixing CI where dists are absent.
