Security updates: this release closes 14 Dependabot advisories across our Ruby and JavaScript dependencies, most notably the Active Storage variant-processing advisory (Rails 8.0.5.1) and four node-tar advisories. We also added the Müsli slice guide and decision maps to the architecture book in #1199 and #1200.
