angle_round_threshold was only assigned inside the `distance > 0` branch of calculate_distance_and_angle, but read unconditionally whenever should_round is True. When the mouse sample coincides with the last placed point (distance == 0), such as the first mouse move after placing a wall's start point on a YZ plane view, this crashed the modal wall tool. angle_round_threshold is a fixed cutoff unrelated to whether distance is currently zero, so it is now assigned once before the branch. Fixes #8597. Generated with the assistance of an AI coding tool.
