On self-hosted runners, _github_home/.gitconfig persists across jobs.
The ocr-review workflow used --add which accumulated multiple safe.directory
values over time. Once multiple values existed, other workflows using plain
git config (without --add/--replace-all) failed with "cannot overwrite
multiple values with a single value".
Unify all workflows to use --replace-all, which clears previous values and
writes exactly one entry regardless of prior state.
