Kirill Bulatov , Thorsten Ball , and Cole Miller created
Part of https://github.com/zed-industries/zed/issues/20925
This prototype is behind a feature flag and being merged to avoid
conflicts with further git-related resturctures.
To be a proper, public feature, this needs at least:
* showing deleted files
* better performance
* randomized tests
* `TODO`s in the `project_diff.rs` file fixed
The good thing is, >90% of the changes are in the `project_diff.rs` file
only, have a basic test and already work on simple cases.
