/**
 * Phase 6: Stop Command Tests
 *
 * Tests the stop command - interrupting agents (no-op if idle) (top-level command).
 * 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:
 * - stop --help shows options
 * - stop requires ID, --all, or --cwd
 * - stop handles daemon not running
 * - stop --all flag is accepted
 * - stop --cwd flag is accepted
