Shipped: directory, feeds, share pages, roadmap, translation

We shipped a distribution-focused batch. Buoylog changelogs now come with a public directory of changelogs, RSS and JSON feeds, shareable per-release pages with auto-generated OG images, a what's-new badge you can embed, a public roadmap board, automatic multi-language translation, and reader reactions. The core stays the same: merge a PR and get a categorized release note without writing it yourself.
