Build me a fast, native desktop launcher that feels like a command palette for power users.

I want it to let me quickly search and open apps, search files, manage clipboard history, use text snippets, switch browser tabs, pick emoji, do quick calculations, switch windows and workspaces, browse fonts, and control volume. It should feel lightweight, polished, and easy to bring up from the keyboard.

Please also make it extensible so I can add extra actions and plugins, and support React and TypeScript based extensions that work with the Raycast ecosystem if possible. If you need to check current docs online while building it, go ahead.

Make it work well on desktop platforms, keep it native and responsive, and include a clean UI that feels like a modern productivity tool rather than a heavy app.
