Investigate how to use workspace packages in the templates

[nikgraf]

Reproduce:

1. make a change in hypergraph
2. test it in the template

It probably doesn't work since the vite/tsconfig setup doesn't include it - which we ideally don't change since it's a template. It probably could work if we build the packages. more investigation is needed

fixed with #507 /cc @baiirun
