📚 Phase 15計画を詳細化・更新: Python/llvmlite正式採用とプラグイン全方向ビルド戦略

✅ 主な更新内容:
- Python/llvmlite実装の正式採用を明記（開発速度10倍、~2400行）
- プラグイン全方向ビルド戦略（.so/.o/.a同時生成）で単一EXE生成可能に
- 各実装の予想コード量を具体化（パーサー800行、MIR Builder 2500行、VM 5000行）
- 循環依存問題の解決を明記（nyrtがC ABI経由で提供）
- 現実的なスケジュール調整（2025年9月～2026年3月）

🎉 最新進捗:
- dep_tree_min_string.nyashオブジェクト生成成功（10.4KB）
- LLVM verifier green - dominance違反解決
- Resolver patternでSSA安全性確保

🚀 次のマイルストーン:
- Python/llvmliteでEXE生成パイプライン完成
- nyash-llvm-compiler分離設計
- NyashパーサーMVP実装開始

Everything is Boxの究極形が、ついに実現へ！
