Hello,

This is my first ever time making a publicly available project on GitHub. Therefore, I am unfamiliar with proper etiquette and legality surrounding licensing, citation and referencing of code.

I have made an effort to provide the repository links to the code which I have used, and stated wherever Artificial Intelligence was used to generate code. I hope this is up to standards.

Otherwise, I appreciate any help in correcting my mistakes!

Thank you.

Please add this as a submodule and we'll take another look. See https://zed.dev/docs/extensions/developing-extensions#publishing-your-extension for a detailed guide on this.

Second question would be why we need the lua definitions if thes just seem to duplicate existing lua ones. Can we not just add the language server?
