Add robots.txt and llms.txt to counterfact.dev

[Copilot]

Summary

Adds two discovery files to site/public/ so they are served at the root of https://counterfact.dev. The goal is to increase findability for both search crawlers and LLMs surfacing relevant tools to developers.

• robots.txt — open to all crawlers, no Disallow rules
• llms.txt — follows llmstxt.org spec: title, blockquote description, extended prose for target audience, and curated link sections for Documentation, Patterns, and Source Code

Original Prompt

Create these two files and add them to the web site. The goal to increase the chances that people interested in the kinds of problems Counterfact solves will find the web site.

Manual acceptance tests

• https://counterfact.dev/robots.txt is reachable and contains User-agent: * / Allow: / with no Disallow directives
• https://counterfact.dev/llms.txt is reachable and begins with # Counterfact
• All links in llms.txt resolve (docs and patterns pages return 200)
• cd site && npm run build completes without errors and dist/robots.txt + dist/llms.txt appear in the output

Tasks

• Added site/public/robots.txt (allow all bots)
• Added site/public/llms.txt with project description, Documentation section (5 links), Patterns section (11 links), and Source Code section
