🎯 VM/JIT同一実行の達成: - InstanceBox: getField/setField完全一致（field3統一API） - StringBox: 文字列リテラル最適化（u64x2）+ len操作一致 - NewBox: グローバルレジストリ経由の統一生成 - 全Box型でVM/JIT結果が完全同一に 技術的実装: - host-bridge拡張: field3（固定3引数）でget/set統一 - 文字列処理: emit_string_handle_from_literal + from_u64x2 - Instance生成: nyash.instance.birth_name_u64x2 thunk - JitEngine経路: LowerCore→CraneliftBuilder統合 テスト強化: - PersonFactory: VM/JIT両系で同一レジストリ使用 - getField/setField: センチネル値(-1)による識別 - 文字列操作: リテラル/Box両対応 これでNyashは「Real Language」として完成！ 同一コードが異なる実行系で完全に同じ結果を保証。 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
