GitHub contributors & bus-factor API

Ranks a repo's top human contributors by commit count (bots excluded), computes each one's percentage SHARE of all commits, and derives the BUS FACTOR — how few people hold 50%+ of the work — with a key-person risk rating (high/medium/low). Answers 'who maintains owner/repo', 'how concentrated is contribution', 'what is the bus factor / key-person risk of this dependency'.
