Phase 12.7文法改革: ドキュメント文法統一 + VMリファクタリング準備

Browse Source 
🌟 Phase 12.7文法改革に基づくドキュメント更新
- init {} → field: TypeBox 個別フィールド宣言形式
- init() → birth() コンストラクタ統一
- pack() → 廃止（birth()に統一）
- public {}/private {} → 個別フィールド修飾子
- override → 廃止（メソッド定義はシンプルに）

📚 更新したドキュメント
- CLAUDE.md: メイン開発ガイド
- docs/quick-reference/syntax-cheatsheet.md: 構文早見表
- docs/reference/language/LANGUAGE_REFERENCE_2025.md: 言語リファレンス
- docs/development/roadmap/phases/phase-15/README.md: Phase 15計画

🔧 VMリファクタリング準備
- vm_methods.rs: VMメソッド呼び出しの分離
- plugin_loader.rs → plugin_loader/: ディレクトリ構造化
- mir/builder/exprs.rs: 式ビルダー分離

📝 新規ドキュメント追加
- 論文戦略・ロードマップ
- Phase 15セルフホスティング準備資料
- Codex Androidセットアップガイド

ビルドは正常に通ることを確認済み！🎉
