Cross-Day Simulation Test Runner for CampusLifeBench

This script tests the cross-day functionality including:
1. Daily reset of location to default position
2. Date announcement at the start of each new day
3. State persistence across days (emails, reservations persist)
4. Location reset while other states persist
5. Multi-day task sequences
