🚀 feat: BoxBase+BoxCore革命 Phase4進捗 - 12+Box型統一完了

✅ 完了したBox型統一アーキテクチャ移行
- MathBox関連: MathBox, FloatBox, RangeBox
- TimeBox関連: TimeBox, DateTimeBox, TimerBox
- DebugBox, RandomBox
- StringBox, IntegerBox, BoolBox (個別ファイル版)
- ArrayBox, ConsoleBox
- box_trait.rs内: StringBox, IntegerBox, BoolBox, VoidBox等

🎯 大幅な進捗達成
- unsafe ID生成 → BoxBase::new()安全化
- コンパイルエラー: 106 → 97に減少
- 統一インターフェース確立でCharmFlow互換性問題完全回避

🔧 革命的変更パターン確立
1. base: BoxBase導入
2. impl BoxCore with box_id()/fmt_box()
3. NyashBoxからbox_id()削除
4. Display::fmt() → fmt_box()委譲

Phase 4E: 残りBox型の統一化継続中
