From each publisher's own tool list. We never call a tool.

Reposcan `co.huggingface.saylortwift/reposcan` Find the most breakage-prone files based on churn and fix-PR frequency. Use this when asked 'what file breaks most often?', 'what are the most fragile files?', 'which files are most risky to touch?', or 'what is the most changed file?'. Requires diffs in the dataset (transformers_with_diffs.jsonl). Reports both raw churn (lines added+deleted) and fix-PR frequency (files touched in bug/fix/regression PRs). Files high on both lists are the riskiest. Returns: str: Two ranked lists — most churned files and most fragile (fix-PR) files.	`top_n`	Not stated
