Umbraco Tiptap Toolbar Extension

What is it?

A Tiptap Toolbar Extension adds buttons or controls to the Rich Text Editor's toolbar. It provides an execute method that runs when clicked, and can indicate active/disabled states. Several "kinds" are available: button (simple toggle), colorPickerButton (color selection), menu (dropdown menu), and styleMenu (style selection dropdown).

Workflow

1. Fetch docs - Use WebFetch on the URLs above
2. Ask questions - Button, menu, or color picker? What action to execute?
3. Generate files - Create manifest + API class based on latest docs
4. Explain - Show what was created and how to test
