Content Audit

Audit hackathon content (tracks, challenges, docs, starter code) for correctness, hallucinations, outdated information, pacing, broken links, and convention violations, then fix what it finds. Verifies claims against official Azure and tooling docs on the internet. Use when asked to 'review the content', 'check for errors', 'find hallucinations', 'is this still accurate', 'verify the docs', 'check links', 'audit a track', 'is this challenge doable in time', 'fact-check this', or before a release
