Updates section

This site now has an /updates feed — one place to follow what's shipping across all the projects, with filters per project and a feed of recent posts on each project page.

Two kinds of posts:

• Releases — terse, changelog-style notes for new versions or features
• Devlogs — longer, narrative posts about what's being built and why
• Note — random musings that may not be directly related to the projects.

Each project page surfaces its most recent entries, with a link through to the full filtered feed.
