refactor: 大規模リファクタリングPhase完了 - SRP原則による品質向上

Browse Source 
🎯 実行内容:
• box_operators.rs: 639行 → 26%構造改善 (Phase 1-2完了)
  - マクロ抽出: macros.rs (演算子実装統一)
  - ヘルパー分離: helpers.rs (共通ユーティリティ)
  - 静的実装分離: static_ops.rs (静的演算子)
• arithmetic boxes: 完全モジュール分割
  - 6種類の演算Box (add/subtract/multiply/divide/modulo/compare)
• plugin_loader_v2: 7モジュール完全分割
  - config/library/metadata/singletons/specs/util分離
• nyash-net-plugin: 緊急修正完了 (27エラー→0)
  - import解決問題・マクロスコープ問題・関数構造問題修正
• nyash-filebox-plugin: モジュール統合・冗長削除

📊 成果:
• SRP原則適用による保守性向上
• 大規模ファイル分割による可読性改善
• プラグインビルドエラー完全解決
• モジュール境界明確化・再利用性向上

🔧 検証済み: 全スモークテスト正常動作確認

/*!
* Box Operations - Binary and unary operations between boxes
*
* This module contains the implementation of operation boxes that perform
* arithmetic, logical, and comparison operations between different Box types.
* This module has been refactored into individual files for better maintainability.
* Each arithmetic operation now has its own dedicated file in the arithmetic/ subdirectory.
