GitHub repo language breakdown API

Converts a repo's raw GitHub language byte counts into a sorted percentage breakdown with total bytes, language count, and primary language. The raw API returns only opaque byte sizes; this normalizes them into shares an agent can rank. Answers 'what languages is owner/repo written in', 'what percent of the code is TypeScript', 'what is the primary language'.
