nyash-codex 83770fa03c docs: Phase 154 MIR CFG integration & HC020 dead block detection specification ...

🎯 ゴール: ブロックレベルの unreachable 検出を hako_check に統合

📋 実装内容:
- Task 1: MIR/CFG 情報インベントリ
- Task 2: DeadBlockAnalyzerBox 設計（箱化モジュール化）
- Task 3: hako_check パイプライン統合設計
- Task 4: テストケース設計（4パターン）
- Task 5: 実装 & テスト
- Task 6: ドキュメント & CURRENT_TASK 更新

🏗️ 設計原則:
- 箱化モジュール化パターン（Phase 153 継承）
- JoinIR/MIR 意味論変更なし（解析は「読むだけ」）
- ENV 追加なし（CLI フラグのみ）

🧪 テストパターン:
- 早期 return 後のコード
- 常に false の条件
- 無限ループ後のコード
- break 後のコード
