Phase A (Python surface): - New mcrfpy.Heuristic IntEnum: EUCLIDEAN, MANHATTAN, CHEBYSHEV, DIAGONAL, ZERO - Grid.find_path() accepts heuristic= and weight= kwargs (weighted A*) - Grid.get_dijkstra_map() accepts roots= (list of positions or DiscreteMap mask) Phase B (FLEE primitives): - DijkstraMap.invert() returns a new map with inverted distance field - DijkstraMap.descent_step(pos) returns steepest-descent neighbor or None DijkstraMap internally switched from the C++ TCODDijkstra wrapper to the C API (TCOD_dijkstra_*) because multi-root compute and invert/get_descent are not exposed on the wrapper. Single-root Dijkstra cache is preserved for backward compatibility; multi-root and mask paths bypass the cache since cache keys would be ill-defined. New tests: heuristic_enum_test, find_path_heuristic_test, multi_root_dijkstra_test, dijkstra_flee_test. Baseline JSONs for dijkstra_bench and gridview_render_bench refreshed against the new implementation. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
