and rejection processes. This ensures that the review lifecycle
correctly finalizes the current pending revision.

- Update `approve` to modify the existing review record
- Update `reject` to modify the existing review record
- Add documentation clarifying when new revisions are created versus
when existing ones are finalized

`changes_requested` state is active.

manage approvals.
