feat(demos): enhance interactive pathfinding demos with entity.path_to()
- dijkstra_interactive_enhanced.py: Animation along paths with smooth movement - M key to start movement animation - P to pause/resume - R to reset positions - Visual path gradient for better clarity - pathfinding_showcase.py: Advanced multi-entity behaviors - Chase mode: enemies pursue player - Flee mode: enemies avoid player - Patrol mode: entities follow waypoints - WASD player movement - Dijkstra distance field visualization (D key) - Larger dungeon map with multiple rooms - Both demos use new entity.path_to() method - Smooth interpolated movement animations - Real-time pathfinding recalculation - Comprehensive test coverage These demos showcase the power of integrated pathfinding for game AI. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
