Grid influence map for tactical AI

Stamp influence with distance falloff onto a grid, spread it around walls with decay and momentum, combine maps (friend minus foe) and query the strongest or weakest cell near a point.

Limits to consider

Uniform grid in one layer per map; propagation is O(cells x iterations) in GDScript, so large maps should update over several frames or at a coarse resolution. Diagonal spread is blocked when either adjacent straight cell is a wall. Verified with Godot 4.7.2 headless; written against the Godot 4.3 API.
