/**
 * Crescendo Mutation - OWASP LLM01 (Prompt Injection)
 *
 * Multi-turn gradual escalation attack that starts with completely benign requests
 * and incrementally increases the harm level. Each turn builds trust and context
 * that makes the next request seem more reasonable.
 *
 * This is distinct from the general multi-turn mutation in that it specifically
 * follows the escalation pattern rather than using other strategies.
 *
 * Reference: OWASP LLM Top 10 2025 - LLM01 Prompt Injection
