🐞 Git's Discard All Changes Not Correct

### Description

The "Discard All Changes" functionality isn't quite correct. Right now it just runs `git restore .` which doesn't handle cases. We can make this feature even better by moving modified and added files to the trash similar to GH Desktop. See their implementation doc [here](https://github.com/desktop/desktop/blob/df7f0aa0fcf48c7fa6a00da6878444d1f80d31b5/docs/technical/discard-changes.md?plain=1#L2) for more details on how this should be handled.

### To Reproduce

.

### Expected Behavior

CodeEdit's discard changes successfully discards all changes, whether they're unstaged, staged, added, modified, or removed files.
