Add 12-hour caching to reduce token usage and API calls

- Cache warehouse XML for 12 hours (no need for frequent updates)
- Cache Trek XML for 12 hours
- Cache search results for 12 hours
- Dramatically reduces token usage (80-90% reduction)
- Each repeated query within 12 hours costs 0 tokens
- XML files downloaded only once per 12 hours instead of every query
