Umbraco Extension Template

This is the official .NET template for scaffolding Umbraco backoffice extensions with TypeScript, Vite, and proper folder structure baked in. You run `dotnet new umbraco-extension -n MyExtension`, optionally add `-ex` for example code including API controllers and dashboard components, then `npm run watch` to start developing. The template handles all the boilerplate so you can jump straight into building sections, dashboards, or custom workspaces. One thing to watch: you must manually add the extension as a project reference to your main Umbraco instance or it won't load, which the skill flags clearly. Solid starting point if you're extending Umbraco's backoffice instead of fighting config.
