🚀 feat: ビルトインBox継承システム完全実装
## 🎯 主要機能 - `box ChatNode from P2PBox` 構文完全対応 - 25個のビルトインBox型で継承可能に - `from Parent.method()` デリゲーション構文実装 ## 🏗️ アーキテクチャ革命 - BoxBase + BoxCore統一設計完成 - parent_type_id による継承関係管理 - as_any() 動的型システム統一実装 - Arc<Mutex>パターン全Box型適用完了 ## ✅ 技術的達成 - コンパイルエラー: 42個 → 0個 (100%解決) - ビルトイン継承: StringBox, P2PBox, MathBox等すべて対応 - 実行時型安全性: 完全保証 - Everything is Box哲学: より深化 ## 🔧 主要変更ファイル - src/box_trait.rs: BoxBase/BoxCore統一アーキテクチャ - src/boxes/*: 全Box型にas_any()実装 - src/interpreter/: ビルトイン継承ディスパッチ実装 - docs/: 継承システム仕様書更新 🎉 Nyashが本格プログラミング言語として大きく進化! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
