Add GEODoctor — open-source evidence-backed GEO audit CLI

[LJMStark]

What

Adds GEODoctor to Utilities & Generators → Open Source Data / Evals.

Why it fits this list

• Open source (Apache-2.0), runs with one command: npx geo-doctor audit yoursite.com — no API key required
• Evidence-backed by design: all 33 audit rules cite public research — the KDD'24 GEO paper (arXiv:2311.09735), the citation-absorption measurement study (arXiv:2604.25707), Vercel/MERJ AI-crawler data, llms.txt spec. Full rule×evidence table in methodology.md
• Scores 5 dimensions (machine access, structure, chunkability, citability, freshness) → 0-100 GEO Score with terminal/HTML/JSON reports
• Bilingual EN/中文 — covers both international and Chinese AI-search ecosystems (incl. Bytespider policy checks)
• Includes a reproducible leaderboard of 11 well-known sites

One line added, matching the existing entry format. Thanks for maintaining this list!
