Module manager 

World-level entity ownership and lookup.

Steel deliberately uses a simpler loaded/simulated split than vanilla’s entity section manager. The manager owns runtime entity lookup regardless of chunk load state; chunks are still the persistence boundary, and only full simulated chunks tick entities.
