Persists the generated Edit project in the user's .cache directory

[jgoodrick]

This is a naive implementation of caching the manifests project. There may be a hashing strategy that is already in use, but I wasn't aware of it yet, if so. That could probably be improved.

Thanks for contributing this one @jgoodrick. I left some minor comments. We can merge the PR once they are addressed.

This will be definitely a great UX improvement 😌

Hey 👋

Sorry for not re-reviewing this PR in a timely manner. The implementation looks good but would you mind adding a couple of unit tests? A new behavior without any raises a red flag 😁

I know we currently don't have tests for this service but can we add some?
