Build me a Rust powered Luau runtime for making standalone desktop apps, with a focus on being lightweight and not feeling bloated like a JavaScript runtime.

I want it to support running Luau scripts from a CLI, building apps into standalone output, and have a practical standard library for everyday app work, like file and folder access, reading and writing data, dates and time, system info, and loading or using media files like images and audio. It should also support requiring local files and simple aliases so app code can stay organized.

Please make it feel usable for real app development, not just a language demo. If anything needs current docs or references, look them up online. Keep the implementation clean and make sure the basic experience works end to end.
