Summary of ChangesHello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed! This pull request introduces a comprehensive example of a mineral processing crusher circuit simulation within the Plugboard framework. It demonstrates dynamic modeling using the Population Balance Model, incorporates a recirculation loop with transport delays, and includes parameter optimization capabilities. Concurrently, it updates the AI agent configurations to better support the development and documentation of such complex examples, enhancing the framework's utility for technical users. Highlights

Code Review
This pull request introduces an excellent, comprehensive example of a crusher circuit simulation, which effectively showcases Plugboard's capabilities for physics-based modeling. The addition of the Jupyter notebook, Python components, and a test script is well-executed. The PR also includes valuable refactoring and additions to the AI agent definitions. I've identified a few potential runtime issues in the new Python code related to error handling and defensive programming. My specific comments provide suggestions to enhance the robustness of the simulation code. These changes should be applied to both the .py module and the corresponding Jupyter notebook. Overall, this is a strong contribution.

There's a potential ZeroDivisionError here if total_mass is 0. This can occur if both feed_mass and recirc_mass are zero. It's important to add a guard to handle this case to prevent the simulation from crashing.

self._selection is not checked for None before being passed to apply_crusher. Since apply_crusher expects a list[float], this could lead to a TypeError if the matrices have not been initialized. It's safer to check for both self._selection and self._breakage before proceeding.

raise RuntimeError("Selection or breakage matrix not initialised")

In some edge cases (e.g., during process startup or shutdown), self.product_psd could be None. This would cause PSD(**self.product_psd) to raise a TypeError. Adding a None check would make this component more robust.
