/**
 * @brief Tests for per-map Eluna instances
 * 
 * These tests verify that:
 * 1. Each map can have its own Eluna instance
 * 2. Map Eluna is created with proper map key
 * 3. Map Eluna respects configuration settings
 * 4. Map Eluna is distinct from global Eluna
 * 5. Instance maps inherit from parent maps
 * 6. Map Eluna lifecycle is properly managed
