guides: add a restrained Featured section to the landing page

Brings back curated highlights without the noise of the old image-card
grid. Featured guides render as a compact row of bordered text cards
(title + 2-line summary, no thumbnails) under a small starred "Featured"
eyebrow, at the top of the content column. It shows only in the default
view (hidden while filtering) and is rendered visible in static markup so
it doesn't pop in on load.

Curation is simple for marketing: set params.featured: true to include a
guide, and weight: N to order them. Seeds a starter trio (GitHub Actions,
Docker Compose, Docker Scout) and clears the stale featured flag on ROS 2.
