refactor(phase115): FileHandleBox 箱化・モジュール化実装完成

Browse Source 
「Everything is Box」原則に基づいて FileHandleBox を整理し、
コード重複を削減して保守性を大幅向上。

【Task 1】テストヘルパー外出し
- tests/common/file_box_helpers.rs を新規作成
- setup_test_file / cleanup_test_file / init_test_provider を共有化
- FileBox と FileHandleBox 両方で統一的なテストヘルパーを使用可能に

【Task 2】ny_* メソッド統一化（マクロ化）
- 4つのマクロを新規定義:
  - ny_wrap_void!（open, write, close）
  - ny_wrap_string!（read）
  - ny_wrap_bool!（exists, is_file, is_dir）
  - ny_wrap_integer!（size）
- 8個のny_*メソッドをマクロ呼び出しに置き換え
- 削減効果: 52行 → 8行（85%削減！）

【Task 3】ドキュメント & テスト確認
- FileHandleBox ドキュメントに "Code Organization" セクション追加
- Phase 115 実装内容を明記（モジュール化・箱化・マクロ統一化）
- CURRENT_TASK.md に Phase 115 セクション追加

【効果】
- 保守性向上: ny_* メソッドの重複パターンをマクロで一元管理
- テスト共有化: 共通ヘルパーで FileBox/FileHandleBox 間の一貫性確保
- 可読性向上: 実装の意図が明確に
- 拡張性: 新しいny_*メソッド追加時はマクロ呼び出し1行で完了

【統計】
- 新規作成: 2ファイル（+40行）
- 修正: 2ファイル（+72行, -62行）
- 実質: +50行（マクロ・ヘルパー・ドキュメント追加）
- テスト: 27個全PASS（1個は環境依存で ignore）

【技術的工夫】
- マクロ展開後の動作が既存と同一（互換性維持）
- エラーハンドリング一元化（unwrap_or_default / unwrap_or(false)）
- allow(unused_mut) で警告抑制

【Phase 106-115 全体成果】
Ring0/FileBox I/O パイプライン第1章完全クローズ
- 10フェーズ完成
- 60ファイル修正
- +2,500行実装
- 59テスト全PASS
- Ring0 / Ring1 / FileBox / FileHandleBox 完全統一設計
