/**
 * Phase 5: Send Command Tests
 *
 * Tests the send command - sending messages to existing agents (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:
 * - send --help shows options
 * - send requires id and prompt arguments
 * - send handles daemon not running
 * - send --no-wait flag is accepted
 * - agent shows send in subcommands
