- Add complete Dijkstra pathfinding to UIGrid class
- compute_dijkstra(), get_dijkstra_distance(), get_dijkstra_path()
- Full TCODMap and TCODDijkstra integration
- Proper memory management in constructors/destructors
- Create mcrfpy.libtcod submodule with Python bindings
- dijkstra_compute(), dijkstra_get_distance(), dijkstra_get_path()
- line() function for drawing corridors
- Foundation for future FOV and pathfinding algorithms
- Fix critical PyArg bug in UIGridPoint color setter
- PyObject_to_sfColor() now handles both Color objects and tuples
- Prevents "SystemError: new style getargs format but argument is not a tuple"
- Proper error handling and exception propagation
- Add comprehensive test suite
- test_dijkstra_simple.py validates all pathfinding operations
- dijkstra_test.py for headless testing with screenshots
- dijkstra_interactive.py for full user interaction demos
- Consolidate and clean up test files
- Removed 6 duplicate/broken demo attempts
- Two clean versions: headless test + interactive demo
Part of TCOD integration sprint for RoguelikeDev Tutorial Event.
