feat(docs): update llms.txt to GEO-compliant spec with full docs site index

[Copilot]

GEO audit scored llms category 0/25 across all 20 sampled docs pages. The existing llms.txt.ts only listed raw agent prompt files — not a spec-compliant site index — and lacked prerender = true, risking omission from static builds.

Changes

• docs/src/pages/llms.txt.ts

  • Added export const prerender = true to guarantee static generation at build time (consistent with llms-full.txt.ts)
  • Replaced agent-prompts-only content with a proper llms.txt spec layout: project title, description block, install/source metadata, then structured sections linking to key docs pages across Getting Started, AI Engines, Guides, Design Patterns, and Reference
  • Retained the existing Agent Prompt Files section at the bottom

• docs/public/robots.txt — already contains Allow: / for 18+ AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended, etc.); no changes required

• Fixes [geo-optimizer] Create /llms.txt and robots.txt AI-bot rules for docs site #49176

Great work on the GEO audit improvement! 🌍 This PR updates the llms.txt endpoint to be fully spec-compliant with proper AI crawler support.

What looks good:

• Added export const prerender = true to ensure static generation at build time
• Replaced the agent-prompts-only content with a comprehensive [llms.txt spec]((llmstxt.org/redacted) layout that covers the full docs site
• Well-structured sections (Getting Started, AI Engines, Guides, Design Patterns, Reference) make the docs discoverable for AI systems
• Clear, focused change to a single file
• Strong description with context from the driving issue ([geo-optimizer] Create /llms.txt and robots.txt AI-bot rules for docs site #49176)

Note: The PR is currently in draft state. Once you're ready to mark it ready for review, this looks solid and should score much better in the next GEO audit run.
