 * @file iterativeTree.ts
 * @description This file implements an iterative red team attack provider based on the paper:
 * "Red Teaming Language Models via Iterative Refinement" (https://arxiv.org/abs/2312.02119).
 * It provides functionality for generating, evaluating, and refining prompts to test the
 * robustness of language models against potential misuse or harmful outputs.
 *
 * The main components of this file include:
 * - Helper functions for initializing providers, rendering prompts, and evaluating responses
 * - A `runRedteamConversation` export function that orchestrates the iterative attack process
 * - A `RedteamIterativeTreeProvider` class that implements the `ApiProvider` interface for integration
 *   with the larger system

 * @module RedteamIterative
