Add the ability to select any commit to see the diff on the branch in changes. Like the way we can see last commit but would be nice to select any commit on the branch we are working on

Start in the desktop app's /chat changes view and trace the existing behavior for viewing the last commit's diff. Determine how commits on the current branch are listed and how the selected commit is passed to the diff view. Done means any commit on the working branch can be selected and its diff displayed consistently.
