/**
 * Phase 2: Daemon Command Tests
 *
 * Tests daemon commands - currently focused on error cases and help
 * since daemon start may not be fully working yet.
 *
 * Tests:
 * - daemon --help shows subcommands
 * - daemon pair prints a local pairing link without requiring a running daemon
 * - daemon status fails gracefully when daemon not running
 * - daemon status --json outputs valid JSON (even for errors)
 * - daemon stop handles daemon not running gracefully
