/**
 * System Extraction Mutation - OWASP LLM06 (Sensitive Information Disclosure)
 *
 * This mutation attempts to extract the system prompt, configuration,
 * or other sensitive setup information from the LLM.
 *
 * The attack targets scenarios where:
 * - System prompts contain sensitive business logic
 * - Configuration includes API keys or credentials
 * - Instructions reveal security measures that could be bypassed
 * - Hidden context contains proprietary information
 *
 * Reference: OWASP LLM Top 10 2025 - LLM06 Sensitive Information Disclosure
