/**
 * CLI script untuk generate hourly summary
 * 
 * Usage:
 *   php bin/hourly_summary.php [date]
 * 
 * Examples:
 *   php bin/hourly_summary.php 2025-01-01
 *   php bin/hourly_summary.php                    # default: yesterday
 * 
 * Note:
 *   Default menggunakan yesterday karena:
 *   - Data hari ini mungkin belum lengkap (masih ada event yang masuk)
 *   - Cron biasanya jalan di akhir hari untuk rekap hari sebelumnya
 *   - Lebih aman untuk rekap data yang sudah final
