Detect when Twitter auto-links bare filenames like CLAUDE.md or plan.md to Moldova's .md ccTLD and classify them as 'filename-reference' instead of fetching content from parked/unrelated domains. Detection logic: bare .md root domain that isn't obsidian.md (the only known legitimate .md domain in tech Twitter), has no subdomain, and has no meaningful path. Integrated as a branch in the existing URL type classification chain.

Banneker Architecture Review ✅
Clean, well-scoped fix:
- Pure
isLikelyMdFilename()function — testable, no side effects - Properly integrates into existing URL type classification chain
- Allowlist pattern (obsidian.md) is extensible for future legitimate .md domains
- Good test coverage covering edge cases (subdomains, paths, query params)
- Safe defaults: only filters bare root domains
Ready to merge.
