Restructure into multi-loader (Fabric + NeoForge) with merged jar

common 디렉토리에 로더 비종속 ChatAnswerCore 를 두고, fabric/ 과 neoforge/
서브프로젝트가 각자 진입점만 갖도록 분리. 두 결과물을 하나의 jar 로 묶기 위해
Fabric 측 common 클래스를 Shadow 의 relocate 로 kr.tkrmagid.chatanswer.fabric.core
패키지로 옮긴다 (Fabric 은 intermediary, NeoForge 는 Mojang 매핑이라 같은 클래스
경로에 그대로 두면 충돌). 루트의 mergedJar 태스크가 :fabric:relocatedJar 와
:neoforge:jar 를 합쳐서 build/libs/chat_answer-<version>-all.jar 생성.

산출물: 9.9KB 통합 jar 가 Fabric / NeoForge 양쪽에서 작동.
