/**
 * Simple Generic Web Agent Workflow
 *
 * Demonstrates the GenericWebAgent pattern:
 * 1. Navigates to a URL
 * 2. Uses GenericWebAgent to extract content with a simple objective
 * 3. No stages - just a one-shot LLM call with browser tools
 *
 * This is the simplest way to use LLM-powered web automation.
