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.
