// WL849_WeaponModels.cs — 무기 래퍼 프리팹 생성(손잡이 기준 확대) + Addressables 등록 · 월드 크기 측정 (에디터 · 멱등)

//   값 = AgentScripts/WL849_WeaponModels.json (C45 · 모델 경로·배율은 여기 없음)
//   unity command run_script --file AgentScripts/WL849_WeaponModels.cs --entry WL849_WeaponModels.Build --timeout 180

//   🔴 원본 PCActor.Make_Weapon 은 인스턴스 루트에 (위치 0 · 크기 1)을 덮어쓴다 → 배율은 루트가 아니라 자식(팩 프리팹 인스턴스)에 둔다.
//      팩 모델의 기준점 = 손잡이 → 자식을 원점에 두고 키우면 손에 쥔 자리는 그대로다.
