Usage: scripts/run_gcp_context_batch.sh [--batch-id ID|--resume-batch ID] [--rows A,B] [--dry-run] [--no-judge]

Runs the canonical seven-row GCP context closeout cohort with stable run IDs,
SMARTGRID_RESUME=1, per-row manifest/state files, and idempotent judge scoring.

Set SMARTGRID_SKIP_LOCAL_MODEL_PREFLIGHT=1 only for hosted-model cohorts
where every row has LAUNCH_VLLM=0.
