Vijay Janapa Reddi 69f330b2db fix(shared): centralize font loading via site-head.html + fix carousel
- Replace inline Google Fonts <link> tags in all 8 site configs with
  a single `- file: shared/config/site-head.html` reference, so fonts
  (Inter 400-800, JetBrains Mono) and Font Awesome are inherited from
  one shared file instead of duplicated across every _quarto.yml
- Add missing Inter weight 800 (was only in site-head.html, not configs)
- Add carousel CSS + JS for MLSys·im landing page (arrows, dots, slides,
  auto-rotation, keyboard nav) — fixes non-functional < > buttons
