This commit adds rudimentary types for the internal lua code. This does not have a big effect on its own, but it can be a part of a bigger effort to add types to the codebase. The types are only usable within yazi itself and are not published for plugin developers to use (yet). I only added types for the things that are defined in the lua side of the codebase. This means most of the useful typing is still missing. I want to add that separately, as it would be difficult to keep the types in sync with the actual codebase.
