microsoft/vscode ? reverse-engineered prompt

Build me a desktop application that's a high-quality code editor, something like Visual Studio Code. It needs to be cross-platform, so it should run on Windows, Mac, and Linux.

The goal is to create an app that's more than just a simple text pad; it should support a developer's full workflow from editing code to building and debugging it. Please include essential features like smart code completion, syntax highlighting for many different programming languages, and easy code navigation. A really important part is building a rich extensibility model, so that users can find and install plugins to add new themes, tools, and support for other languages.

It should feel lightweight and simple to use but be powerful underneath. Use modern, reliable technologies like TypeScript to build it. The final product should look and feel polished and professional.
