🚨 AI協調開発の危機回避事例を論文化（paper-09）

Browse Source 
「ん？大丈夫？」の一言がPython特化ハードコーディングを防いだ事例を記録。
Everything is Box哲学 vs 技術的正しさの綱渡りからの生還を分析。

- docs/research/paper-09-ai-collaboration-pitfall/ を新規作成
  - incident-analysis.md: Lowerer特殊化危機の詳細分析
  - ai-collaboration-lessons.md: AI協調開発の教訓
  - intuition-in-engineering.md: エンジニアの直感の価値
  - summary.md: 綱渡りからの生還まとめ
- 研究論文の1論文1フォルダ原則に従い整理
- Python統合関連の実装修正とビルド成功確認
