Move website publish root from static/ to repository root

[Copilot]

The site was structured around a static/ subdirectory while deployment and runtime needed the project root to be the canonical web root. This change re-roots the published site and aligns runtime/deploy/docs to that layout.

• Repository layout migration

  • Moved web entry/assets from static/ to root: index.html, 404.html, css/, js/, CNAME, .nojekyll
  • Removed the now-empty static/ directory

• Runtime serving alignment (Flask)

  • Updated app.py to serve static assets from repository root (static_folder='.', static_url_path='')
  • Simplified / route to serve root index.html directly

• Deployment alignment (GitHub Pages)

  • Updated workflow publish target from ./static to . in .github/workflows/deploy.yml

• Documentation updates

  • Updated README.md project layout and GitHub Pages notes to reflect root-based publishing and file locations

  publish_dir: .
