Our ID shortening approach is a wee bit aggressive. We should instead take an approach more like jujutsu, where we call out the shortest unique prefix with an accent colour, but default to including eight characters total. Those from the prefix up to eight are in a muted colour. I'm not sure what jj does when the shortest unique prefix in a repo is longer than 8 chars 🤔
See #12 for an example of what I mean.
