Create a one stop shop config file

[aruniverse]

Currently there are multiple places you need to edit to get started.

Eg:

• pnpm-workspace.yaml
• *.code-workspace
• package.json for overrides (and patches from sub repos)

need to manually clone repos,
for every repo need to manage its branch state

• would be nice to be able to set the sha of a commit to use or a branch to use as reference

Would be nice to have a single file that can be used for everything above as the single source of truth
