/**
 * Phase 3: LS Command Tests
 *
 * Tests the ls command - listing agents (top-level command).
 * Since daemon may not be running, we test both:
 * - Help and argument parsing
 * - Graceful error handling when daemon not running
 * - JSON output format
 *
 * Tests:
 * - paseo --help shows ls command
 * - paseo ls --help shows options
 * - paseo ls returns empty list or error when no daemon
 * - paseo ls --json returns valid JSON (or error)
 * - paseo ls -a flag is accepted
 * - paseo ls -g flag is accepted
 * - paseo ls does not support --ui
