Code Review

This pull request significantly improves the project's structure and documentation. Moving the simple_chat example to the standard example/ directory is a great change that follows Dart conventions. The added documentation in the core genui classes and the new examples/examples.md overview are also valuable additions.

One suggestion is to rename example/example.md to example/README.md to follow standard project structure and improve discoverability on platforms like GitHub.

I've added one specific comment on the newly added examples.md file.

Thanks so much for this cleanup!

We would prefer to keep all the examples together in a folder.

What if you keep simple_chat where it is, but then rename examples to example, and add the readme that you already created at example/README.md. I'm not 100%, but based on https://dart.dev/tools/pub/package-layout#examples, I suspect this will create the example tab in the UI and hopefully give us the 10 points :-D.
