/**
 * @brief Tests for Creature Eluna delegation
 * 
 * These tests verify that:
 * 1. Creatures can access Eluna through their map
 * 2. GetEluna() delegates to map's GetEluna()
 * 3. Creatures get same Eluna as their map
 * 4. Null map handling is graceful
 * 5. Multiple creatures on same map share Eluna
 * 6. Creature Eluna is distinct from global Eluna
 * 7. Creature Eluna persists with creature lifetime
