/**
 * This file provides a function to initialize a Stagehand instance for use in evaluations.
 * It configures the Stagehand environment and sets default options based on the current environment
 * (e.g., local or BROWSERBASE), caching preferences, and verbosity. It also establishes a logger for
 * capturing logs emitted by Stagehand.
 *
 * We create a central config object (`StagehandConfig`) that defines all parameters for Stagehand.
 *
 * The `initStagehand` function takes the model name, an optional DOM settling timeout, and an EvalLogger,
 * then uses these to override some default values before creating and initializing the Stagehand instance.
