docs: replace all CardGroup/Card blocks with animated bullet points across all 50 docs pages (#648)

- Fix What's new → link in Info banner (now a proper <a> tag, always clickable)
- Replace 4-stat CardGroup on index with inline premium stats row
- Convert every <CardGroup>/<Card> block site-wide to markdown bullet lists:
  content sections → bold-title bullets with sub-bullets, nav cards → [Title](href) — description
- Add cursor-animated list item hover effects to custom.css:
  green inset left border, subtle background tint, marker color change on hover
- Affects index, getting-started, quickstart, concepts, modules, faq, architecture,
  installation, cookbook, glossary, learning-more, explorer-setup, cli-setup,
  community, contributing-guide, governance, citation, project-license,
  all integrations pages, and all 20+ reference module pages
