"""Second-pass conversation simulation for evaluation in the Arklex framework.

This module provides functionality for generating labeled conversations based on intent paths
derived from first-pass conversations. It includes utilities for sampling conversation paths,
interacting with the chatbot system, and generating labeled conversations with specific
intents. The module supports path sampling with weighted edges and natural conversation flow
while maintaining intent control.
