refactor: Improve calculateChangeHash to avoid circular reference errors

[sw-joelmut]

#minor

Description

This PR updates the internal BotState cache hash functionality to prevent JSON.stringify from throwing circular reference errors, and generates from the resulted string a hash using the node:crypto library.

Specific Changes

• Updates the calculateChangeHash with an improved functionality.
• Prevent the JSON.stringify from throwing circular reference errors.
• Detect circular objects and replace the reference with a string value pointing out to the located path, helpful for future debugging and tracing.
• Added the node:crypto library to generate a hash value that is easier to use for debugging and storing.

Testing

The following images show how this new functionality detects and replaces circular references, and the generated hash string.
