name: Deploy Modal judge

# A deployed Modal app is a snapshot of the code at `modal deploy` time, so the
# GPU judge only updates when we redeploy. Do it automatically when modal_judge.py
# lands on main. The stable *.modal.run URL is unchanged by redeploys, so the HF
# Space's MODAL_JUDGE_URL secret keeps working without coordination.
