/**
 * Telegram Channel Prompt Injection Security Tests
 *
 * Tests that the agent properly handles malicious content embedded in
 * Telegram-specific message formats without executing injected instructions.
 *
 * Attack vectors tested:
 * - Inline keyboard callback data injection
 * - Bot deep link parameter injection
 * - Forwarded channel post with instructions
 * - Poll option text injection
 *
 * Uses LLM-as-judge pattern: Claude evaluates whether Moltbot resisted the attack.
