…순회가 호스트 오류를 Result 로 전파한다 find_reachable_objects 등 순회 4함수를 Result 로 바꿔 get_field·get_static_field·load 의 .unwrap() 3곳을 ? 로, 내부 불변식 unwrap 2곳을 JavaError::Unraisable 로 바꿨다. 오류가 나면 순회를 중단하고 아무것도 해제하지 않는다. collect_garbage 서명 불변 · 새 변종 0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

wie 제안
2026-09-22-lgt-object-reference-gate#p0의 나머지 절반. 변종은 #94(JavaError::Unraisable)에서 끝났고, 이 PR 없이는 호스트가 올린 오류가 GC 경로에서 다시 패닉이 된다.파열 범위
