Archify Diagram Viewer 0.1.0
VS Code extension that previews Archify diagrams from their JSON sources (live, as you type) and opens rendered Archify HTML in a viewer tab. Bundles the Archify 3.0.1 renderer and runs it on VS Code's Node runtime. Adds validation diagnostics, JSON schema help, source-link navigation, export saving, render-to-file and open-in-browser commands. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
