🎉 merge: Arc<Mutex>革命をmainブランチに統合完了！

## 🔥 統合された革命的成果
- **全9種類のBox統一**: Arc<Mutex>パターンで内部可変性実現
- **&selfメソッド**: すべてのBoxで統一されたメソッドシグネチャ
- **スレッドセーフ**: マルチスレッド環境で安全動作保証
- **メモリ安全**: Rustの所有権システムと完全統合

## ✅ 統合されたBox実装
- ArrayBox: Arc<Mutex<Vec<dyn NyashBox>>>で配列操作
- BufferBox: Arc<Mutex<Vec<u8>>>でバイナリデータ処理
- RegexBox: Arc<Regex>で正規表現処理
- JSONBox: Arc<Mutex<Value>>でJSON解析・操作
- StreamBox: Arc<Mutex<Vec<u8>>>でストリーム処理
- HttpClientBox: HTTP通信（stub実装）
- ResultBox/FutureBox: エラー・非同期処理（確認済み）

## 🏗️ アーキテクチャ革新
- **"Everything is Box"哲学の完全実現**
- **GitHub Copilotとの協働成果をmainに統合**
- **統一されたArc<Mutex>パターン**
- **内部可変性と外部安全性の両立**

🎊 Arc<Mutex>革命 - mainブランチ統合完了記念日: 2025年8月10日
