- Add next_check_at column to track when each product should be checked
- New products get random initial delay (0 to refresh_interval) to spread them out
- Each check adds ±5 minute jitter so products naturally drift apart over time
- Randomize delay between requests (2-5 seconds instead of fixed 2s)
This prevents all products from being checked at the same time,
reducing the risk of being rate-limited or blocked by retailers.
