Add clear documentation for handling agent retries and timeouts

[lad-sharper]

Overview

AgentKit works with different tasks, but it doesn't clearly explain how to set up agent retries and timeouts. This makes it harder for developers to adjust these settings and may cause unexpected issues.

Without clear instructions, developers may:

• Have trouble setting up retries and timeouts properly.
• Experience agents timing out or retrying too many times.
• Not know how to handle issues like slow APIs or network problems.

Proposed Solution

Add a section to the documentation that explains how to set up retries and timeouts. Include examples for different situations, like retrying tasks or managing timeouts for slow services.
The documentation should make it easy for developers to understand and configure retries and timeouts. Developers should be able to use these features without confusion or errors.
