Clarify best practices for managing multiple agents in a single application

## Overview
The current documentation lacks clear guidance on how to manage multiple agents effectively within a single application, which may confuse developers integrating multiple agents or tools.

### Problem Description
Developers integrating multiple agents into a single project may struggle to:
- Coordinate state across different agents
- Avoid conflicts or overlapping functionality
- Ensure scalability and maintainability as the project grows

### Proposed Solution
- Add a section to the README explaining best practices for managing multiple agents in one application, including state management and organizational patterns.

### Acceptance Criteria
- Documentation includes clear guidance on how to manage multiple agents.
- Developers can easily apply the suggested patterns to maintain clean and scalable code.
