fortawesome/font-awesome ? reverse-engineered prompt

Build me the Font Awesome Free v7 icon toolkit from this repo, so people can use the same icons as SVGs, CSS classes, sprites, and web fonts in their websites. I want the project to include the icon files, the stylesheet and JavaScript helpers, and a clean way to package and serve the different icon formats so they are easy to drop into a front end project.

Also make sure there is a simple README style setup that shows how to use it, how to upgrade from older versions, and how to include the icons in a normal web app. Keep it polished and ready for real use, with the assets organized clearly and the build working without extra manual steps. If you need to check current docs or best practices online, go ahead and look them up.
