Blame for scripts/patch_v1_1.py

# One-off patch of the dataset's v1.0 shards to v1.1 (lead, 2026-11-05): conclusion columns in the readout's kinds
# (target_score + grader_rules -> grader; hedge folded by build_dataset.conclusion) and the prefill "hedge" condition
# dropped. Same shards, schema and compression; rewrites build_report.json counts.
# Usage: python patch_v1_1.py <dataset folder>
