Build me a Fabric mod for a Minecraft dedicated server that brings Folia style region based multithreaded ticking to vanilla servers.

I want it to load like a normal Fabric mod, not require a custom server jar, and split the world into independently ticking regions that can run in parallel on a bounded worker pool. Please keep the core concurrency engine separate from the Fabric facing bits so the scheduler and region logic can be tested on their own, and make the mod package self contained so it ships as one jar.

It should include a small admin command set for checking status, regions, threads, compatibility, and shutting the server down cleanly. Also generate a first run config file with helpful comments, preserve user comments when saving, and don’t silently drop unknown settings.

If you need to, look up current Fabric or Minecraft docs online for anything version specific.
