Add debouncing and caching

Tell Lovable to add proper API management:

Copy this prompt

The app is hitting rate limits on external API calls. Please add:
1. Request debouncing for search inputs (300ms delay)
2. Response caching with a 5-minute TTL
3. Error handling that shows a friendly message when rate limited
4. Exponential backoff for retried requests

Prevent this next time

Always debounce search inputs and cache API responses. Include this in your founding prompt when using external APIs.

Frequently Asked Questions

Waiting a short time (e.g. 300ms) after the user stops typing before making the API call. This prevents firing 20 requests while someone types a search query.

Saving API responses temporarily. If the same data is requested again within 5 minutes, serve the saved version instead of hitting the API again.
