/**
 * Phase 14: Worktree Command Tests
 *
 * Tests the worktree commands for managing Paseo-managed git worktrees.
 * 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:
 * - worktree --help shows subcommands
 * - worktree ls --help shows options
 * - worktree ls handles daemon not running
 * - worktree archive --help shows options
 * - worktree archive requires name argument
 * - worktree archive handles daemon not running
