/**
 * Phase 9: Inspect Command Tests
 *
 * Tests the inspect command - showing detailed agent information (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:
 * - inspect --help shows options
 * - inspect requires id argument
 * - inspect handles daemon not running
 * - inspect --host flag is accepted
 * - agent shows inspect in subcommands
