Integration with Jujutsu

Jujutsu (or jj) is a git compatible distributed version control system (DVCS). When working in a repository managed by Jujutsu, Helix will not display any gutter change indicators, as that functionality currently works with a standard git repository.

Support may be relatively simple, see https://github.com/martinvonz/jj/blob/main/docs/github.md#using-github-cli (using .jj/repo/store/git)
