Add Markdown figure support

This adds a project-local Markdown figure plugin so blog posts can use
semantic `<figure>` blocks with arbitrary CSS classes, optional
captions, and Markdown inside captions.

The image CSS is also updated so figures share the existing width,
breakout, float, centering, and rounded-image utilities while keeping
captions styled and spaced consistently with the rest of the article
layout.
