seo: fix theme-color, speakable selectors, llms.txt /guide/ → /docs/

- theme-color updated to Zinc bg (#09090b) — was Slate dark (#060b18)
- SpeakableSpecification removes stale .faq-answer (FAQ moved to /faq/)
  replaces with .problem-intro for better AI readability signals
- llms.txt: all /guide/ URLs updated to /docs/ for consistency
- Add llms.txt to git tracking (GEO signal for AI crawlers)
- robots.txt: LLMs: directive already present
