Replace Quarto site with static HTML generator

- Add site/generate.py: static site with search, filtering, sorting, dark mode
- Add site/static/style.css and main.js for the new frontend
- Extend parse.py: fetch CRAN published dates, PyPI release dates, and
  discover GitHub repos from CRAN pages as fallback data sources
- Migrate from Poetry to uv (pyproject.toml + uv.lock)
- Update CI workflow to use uv and generate.py pipeline
- Add CONTRIBUTING.md with entry format guidelines
- Add "Submit a Project" button to site nav
- Update review-pr skill with all accepted entry formats
- Update CLAUDE.md to reflect new architecture
- Remove Quarto files (_quarto.yml, *.qmd, sync-site skill, poetry.lock)
