💡 How It Works

1. User adds keywords via /add 70-200 — this tells the bot to watch for titles containing "70-200"
2. User sets alert channel via /monitor in the desired Discord channel
3. Bot auto-scrapes both PTT DC_SALE and DCView Market every 90 seconds
4. New listings matching keywords trigger a rich embed alert in the Discord channel
5. Deduplication ensures you only get notified once per listing
