/**
 * E2E Test: Agent Send Command
 *
 * This test verifies the `send` command using REAL daemons and agents.
 * It starts an isolated daemon on a random port and runs actual CLI commands.
 *
 * Test flow:
 * 1. Start daemon on random port
 * 2. Create agent with detached mode
 * 3. Wait for agent to become idle (initial task complete)
 * 4. Send new message with `send`
 * 5. Wait for agent again
 * 6. Verify agent processed the message (check logs)
 * 7. Cleanup
 *
 * CRITICAL RULES:
 * - NEVER use port 6767 (user's running daemon)
 * - Always use claude provider with haiku model for fast, cheap tests
 * - Clean up resources after test completes
