Subject: [PATCH] =?UTF-8?q?v1.3.0=20=E2=80=94=20single=20jar=20covers=20Fa?=
 =?UTF-8?q?bric=201.21.6=20+=20Fabric=2026.1.2=20+=20NeoForge=201.21.6?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

이전엔 1.21.6 (v1.1.1) 와 26.1.2 (v1.2.1) 가 분리된 jar 였음. 사용자 입장에서
버전별로 다른 파일을 받아야 했고 합친 의미가 없어서, 한 jar 가 어느 환경에든
들어갈 수 있도록 컨테이너 구조로 재작업.

구조:
  - outer chat_answer-1.3.0.jar
    ├── fabric.mod.json         (entrypoint 없는 컨테이너 메타. MC dep 없음.)
    ├── META-INF/neoforge.mods.toml  (NeoForge 1.21.6 모드 본체 메타)
    ├── kr/.../neoforge/        (NeoForge 1.21.6 entry + core, Mojang 매핑)
    ├── kr/.../core/            (NeoForge 가 쓰는 공유 core 사본)
    └── META-INF/jars/          (Fabric Loader 가 자동 스캔)
        ├── chat_answer-fabric-1216-1.3.0.jar  (MC ">=1.21.6 <1.22")
        └── chat_answer-fabric-2612-1.3.0.jar  (MC ">=26.1.2")

로더별 동작:
  - Fabric 1.21.6  → outer 는 no-op 컨테이너, 1216 nested 가 활성 (intermediary class_NNNN 리매핑됨)
  - Fabric 26.1.2  → outer 는 no-op 컨테이너, 2612 nested 가 활성 (intermediary 0.0.0 identity)
  - NeoForge 1.21.6 → outer 의 NeoForge entry 가 동작. Fabric 메타와 nested jars 는 NeoForge 가 무시.

핵심 트레이드오프:
  - 1.21.6 fabric subproject 는 modImplementation 필수 (intermediary 매핑 리맵 필요)
  - 26.1.2 fabric subproject 는 implementation 으로 충분 (서버 jar unobfuscated → identity 매핑)
  - 26.1.2 NeoForge 는 moddev plugin 이 아직 26.x 를 파싱 못 함 → 1.21.6 만 지원
  - 두 nested fabric jar 는 mod id 동일 (chat_answer_fabric) — depends.minecraft 가 상호 배타라
    한 환경에서 둘이 동시 candidate 가 되지 않으므로 충돌 없음.
