### 🔧 Modular Design

- **`core/`**: Handles WhatsApp client logic and session management.
- **`features/`**: Extend your module with new capabilities like sending messages, reading chats, or group management.
- **`index.js`**: Public entry point — imports internal features and exposes usable functions.

This design ensures it's easy to grow your package while keeping the codebase clean and maintainable.
