Behavior
- First run: fetches current deals and records them in the database without posting (avoids spamming the room with existing deals)
- Deduplication: deals are tracked by game ID + timestamp; duplicates are never reposted
- Pruning: deals older than 30 days are pruned from the database so they can be reposted if they return
- One message per deal: each deal is posted individually so messages are independently linkable and dismissible
- Multi-currency pricing: deal prices are shown in USD, CAD, EUR, and GBP using live exchange rates from the Frankfurter API (ECB data, no API key required). Rates are cached and refreshed hourly.
