📚 Phase 12: Nyashスクリプトプラグインシステム設計と埋め込みVM構想

Browse Source 
## 主な成果
- Nyashスクリプトでプラグイン作成可能という革命的発見
- C ABI制約の分析と埋め込みVMによる解決策
- MIR/VM/JIT層での箱引数サポートの詳細分析

## ドキュメント作成
- Phase 12基本構想（README.md）
- Gemini/Codex先生の技術分析
- C ABIとの整合性問題と解決策
- 埋め込みVM実装ロードマップ
- 箱引数サポートの技術詳細

## 重要な洞察
- 制約は「リンク時にC ABI必要」のみ
- 埋め込みVMでMIRバイトコード実行により解決可能
- Nyashスクリプト→C ABIプラグイン変換が実現可能

Everything is Box → Everything is Plugin → Everything is Possible!
