- Move gas poisoning from Gas.move() to Gas.collisions() so all rats are registered in the collision system before the poison query runs. - Shrink gas and explosion bboxes so rats must be well inside the tile to be poisoned/killed. - Use AABB overlap instead of partial_move threshold for gas poisoning. - Draw mobile units first, then top-layer effects (gas, mines, bombs, explosions) so rats appear under the gas. - Add draw_on_top hint to Unit base class and top-layer units.
