Summary

Add a Code Review panel diff source that shows only unstaged Git changes.

Problem

The Code Review panel currently lets users review all uncommitted changes or compare the current branch against another branch. When a repository has both staged and unstaged changes, there is no apparent way to narrow the Code Review panel to only the changes that have not been added to the Git index yet.

This makes it harder to review the remaining working-tree changes separately from work that has already been staged for commit.

Reproduction steps or desired workflow

1. Open Warp in a Git repository with both staged and unstaged changes.
2. Open the Code Review panel.
3. Use the diff source dropdown that currently supports uncommitted changes and branch comparisons.
4. Select a new option such as "Unstaged changes".
5. Review only changes that would appear in git diff, excluding staged changes that would appear in git diff --staged.
