When the action logs commit history to the runner output, any GitHub Actions workflow commands (e.g. ::set-output::, ::error::, ::warning::) present in commit messages are interpreted by the runner. This can cause unexpected side effects or CI failures. Wrap the history output in a ::stop-commands:: / ::<endtoken>:: pair so that workflow commands in commit messages are printed literally instead of being executed.
