Feedback from #feedback-app: git diff chip stats do not match what the code review panel shows when multiple repositories are present; expected behavior is to reflect the active repository context.

Thread notes current behavior can match one repo but not the active one.

What needs to be done:

• Reproduce with multiple repos/worktrees in a tab
• Verify how diff chip selects source repo versus code review panel repo
• Align chip stats with active repo context used by code review panel
