Looks pretty good imo, thanks for the work! (I'm also kinda interested in how copilot reviews work, so Imma just request a review from copilot rq, first time trying it)

Pull Request Overview

This PR refactors the Lua API integration by moving the log, server, and events tables into their own structs implementing mlua::UserData for better separation of concerns.

• Introduces separate Lua userdata structs for log, server, and events
• Updates the runtime to reference these new structs instead of inlined function definitions
• Adjusts module exports accordingly in the lua module

The events table is being set using an empty key, which is likely unintended. Consider using a meaningful key (e.g., "events") or verifying this is the intended behavior.

Suggested change

	events_table.set("", structs::Events)?;
	events_table.set("default", structs::Events)?;
