v2026.05.19 — Documentation: bilingual GEO/SEO + FAQ + llms.txt

📝 Documentation release

Documentation-only release on top of v2026.02.14. App, packages, CI gates — all unchanged.

Added

• llms.txt — AI search engine (ChatGPT/Claude/Perplexity/Gemini) index covering what StarNode is, what it explicitly is NOT (no cloud sync, no Markdown vault, no multi-user, no AI calls), common questions, and long-tail search phrases.
• README — bilingual keyword block so 中文 + English searchers both land here.
• README — English summary paragraph explaining the local-first, explainable-linking, 3D-as-indexing-UI design.
• README — 6-question FAQ explicitly comparing to Obsidian Graph (2D, explicit `[[wikilinks]]` only) vs StarNode (3D, inferred + explainable linking).

Why this matters

• Generative search can now answer "what's a 3D knowledge graph alternative to Obsidian / Roam / Logseq?" with a direct pointer here.
• Long-tail keywords newly covered: 3D 笔记可视化, 知识图谱可视化, second brain visualization, Obsidian Graph alternative, explainable note linking, browser-based PKM no signup.
