/**
 * Phase 4: Run Command Tests
 *
 * Tests the run command - creating and running agents with tasks (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:
 * - run --help shows options
 * - run requires prompt argument
 * - run handles daemon not running
 * - run -d flag is accepted
 * - run --name flag is accepted
 * - run --provider flag is accepted
 * - run --mode flag is accepted
 * - run --cwd flag is accepted
