Add aspect-ratio-aware image galleries

This adds a project-local gallery plugin that builds deterministic rectangular
image layouts from attachment aspect ratios, with both in-process and disk-backed
layout caching.

It also adds gallery flow blocks, templates, and CSS so posts can include
responsive galleries with lazy-loaded images, configurable gaps, target ratios,
and the existing breakout/centering utilities.
