Fix GitHub Pages 502: add .nojekyll and root index.html

[Copilot]

actions/deploy-pages was receiving GitHub's HTML 502 error page instead of a JSON API response, caused by the Pages pipeline attempting Jekyll processing on a 749KB README.md with no static entry point to fall back to.

Changes

• .nojekyll — disables Jekyll entirely; forces static file serving, eliminating the processing timeout that triggered the 502
• index.html — adds a root entry point with links to all content sections (paper, equations, proofs, figures, etc.), removing the ambiguity of a no-index static site
