`sprout envfile` サブコマンドの実装が完了しました。

### 実装内容

1. **新規ファイル作成**
   - `src/sprout/commands/envfile.py` - envfileコマンドの実装

2. **既存ファイル更新**
   - `src/sprout/cli.py` - envfileコマンドの登録
   - `CHANGELOG.md` - 新機能の記録

3. **テスト追加**
   - `tests/test_envfile.py` - 包括的なユニットテスト

### 機能確認

- ✅ 現在のディレクトリから再帰的に `.env.example` を検索
- ✅ 各 `.env.example` から `.env` ファイルを生成
- ✅ プレースホルダーの処理（`{{ auto_port() }}`, `{{ branch() }}`, `{{ VARIABLE }}`）
- ✅ `--force` オプションで既存ファイルの上書き
- ✅ `--dry-run` オプションでプレビューモード
- ✅ `--silent` オプションで出力抑制
- ✅ lint/formatチェック通過
- ✅ 全72テスト通過

既存の `parse_env_template` 関数を活用してテキスト処理を行い、CLI部分のみを新規実装する形で、効率的に実装できました。

+- `envfile` command to create `.env` files from `.env.example` templates recursively in the current directory without creating worktrees
+- `--force` flag for `envfile` command to overwrite existing `.env` files
+- `--dry-run` flag for `envfile` command to preview what would be created without actually creating files
+- `--silent` flag for `envfile` command to suppress output except for prompts
