 * UFOMovementController - Handles UFO movement and wandering logic
 *
 * Extracted from UFOSystem - handles all the complex movement behaviors:
 * - Curved wandering paths with turn rate variation
 * - Edge avoidance with smooth steering
 * - Click target navigation
 * - Celestial event detection and reaction
 * - Idle behaviors (look around, yawn)
