## Problem

The engineering analytics team is identifying the developer who most consistently lands big commits. Within 2025, group commits by month, then within each month rank them by lines added (largest first, no skipped ranks). For each author, count how many times they appear in a month's top ten across the year. Return the single author with the highest count, with ties broken alphabetically.
