/**
 * Phase 10: Agent Mode Command Tests
 *
 * Tests the agent mode command - changing and listing agent operational modes.
 * Since daemon may not be running, we test both:
 * - Help and argument parsing
 * - Graceful error handling when daemon not running
 * - All flags are accepted
 *
 * Tests:
 * - agent mode --help shows options
 * - agent mode requires id argument
 * - agent mode handles daemon not running
 * - agent mode --list flag is accepted
