Expose Custom Agents and Tools in the Bee API

[matiasmolinas]

Description

It would be great to have the ability to expose custom agents (e.g., the RePlan agent or a custom agent from the Bee Framework examples folder) and custom tools through the Bee API.

Currently, I found a [tutorial](https://github.com/i-am-bee/bee-api/blob/main/docs/add-native-tools.md) explaining how to expose tools by adding them to the Bee API. However, it's not entirely clear how to make these tools available in the Bee-Python SDK after following the tutorial.

Request

1. Example for Exposing Custom Tools
   Could we include an example demonstrating how to expose a custom tool via the API and access it using a simple Python client? This would make the tutorial more accessible and practical for developers.

2. Support for Custom Agents
   Bee Framework allows creating different types of agents. Could the documentation or examples be updated to explain how to:

   • Modify the API to expose a different default agent for the Bee-Python SDK (e.g., a RePlan agent or a custom agent).
   • Use a Python client to interact with such custom agents via the API.

Purpose

These enhancements would provide clarity and guidance for developers looking to extend the Bee Framework with custom agents and tools, making the API more versatile and developer-friendly.

If this is the right approach, I’d be happy to take on this issue. If not, I’d appreciate any feedback on the best way to achieve these goals. Based on your suggestions, I can adapt and take on the issue accordingly.

Thanks in advance for your guidance!
