Subject: [PATCH] Refactor: Optimalkan Kinerja Bot Secara Menyeluruh

Menerapkan beberapa optimisasi kinerja kritis di seluruh codebase untuk secara signifikan mengurangi latensi, penggunaan CPU, dan operasi I/O.

Perubahan Utama:

1.  **Penanganan Perintah yang Efisien:** Mengganti loop penanganan perintah O(n) di `system/handler.js` dengan pencarian berbasis `Map` O(1). Ini secara drastis mempercepat waktu respons perintah. Sistem `case.js` yang usang juga telah dinonaktifkan.

2.  **Optimalisasi Database:** Merefaktor `lib/database.js` untuk menghilangkan operasi baca/tulis file yang memblokir dan berlebihan pada setiap pesan. Operasi sekarang bersifat asinkron dan hanya memodifikasi data dalam memori, dengan penyimpanan yang terjadi secara berkala.

3.  **Menghapus Hot-Reload yang Tidak Efisien:** Menonaktifkan `setInterval` di `index.js` yang memuat ulang semua plugin dan scraper setiap 2 detik, yang menyebabkan beban CPU dan I/O yang konstan.

4.  **Inisialisasi Cron Job yang Benar:** Memindahkan logika penjadwalan `cron` dari handler pesan ke `index.js` untuk memastikan hanya diinisialisasi sekali saat startup.
