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