Docker Compose 構成をシンプル化: 本番=docker-compose.yml、開発=docker-compose.develop.yml

- docker-compose.yml を本番用に変更（旧 docker-compose.prod.yml の内容）
- docker-compose.develop.yml を新規追加（開発用）
- deploy.sh を追加（本番デプロイスクリプト）
- develop.bat を追加（ローカル開発起動スクリプト）
- docker-compose.prod.yml を削除
- 本番サーバーに .env → .env.production シンボリックリンク設置済み
- CLAUDE.md のデプロイコマンドを更新
