      summary: Restart Single ID
      description: >
        Restart a failed workflow run from the DLQ. The workflow will start from
        the beginning.


        Unlike resume, which continues from where the workflow failed, restart
        executes the entire workflow

        from the first step. A new workflow run ID is generated and all steps
        will be executed again.
