CCQ_Core

Fixed chunk generation failing when C2ME and Spartan Weaponry Unofficial are both installed. Structure placement runs on a C2ME worker thread, while Spartan Weaponry rolled zombie, piglin, skeleton, wither skeleton, and piglin brute spawn weapons with the server thread's world random. C2ME then aborted feature placement, and those chunks never finished generating. Spawn-weapon rolls on a C2ME worker thread now use a thread-local random source. Rolls on the server thread are unchanged. The change applies only when Spartan Weaponry Unofficial is installed. C2ME is not required.
