Build me a small Unity project that shows how to automatically test and build the game with GitHub Actions.

I want it to be a clean example project I can open in Unity, run locally, and also have the workflow handle tests and builds in CI. Please set it up so the project is easy to understand, with the Unity settings and a simple sample scene or basic content if needed, but keep it lightweight since this is mainly an example repo.

Make sure the automation is wired up in a way that works for a real Unity project, and include whatever config is needed so someone can clone it and see the full flow from editor to CI. If there are any current best practices or docs that would help, look them up online and follow them.
