Problem

Within repo_commits scoped to year 2025, group by strftime('%Y-%m', commit_at) and rank commits by added descending with a no-gaps rank. Keep rows with rank 10 or less. Per author, count how many of their rows land in that top-10 set across all months. Return one row: the author with the highest count and that count. Break ties alphabetically by author.
