create_finger_joint
Create a finger joint between two overlapping boards. Configure depth, width, height, and offsets to position the joint relative to board face centers.
Instructions
Create a finger joint (box joint) between two boards.
All dimensions in millimeters; offsets shift the joint from the board face's center. Defaults are sized for ~100 mm boards. The two boards must already touch/overlap along the joint axis.
Returns: JSON {board1: {id, name, type, bbox_mm|null}, board2: {...}, boolean_cuts: {attempted, failed}} — non-zero failed means some cuts did not apply (likely non-manifold geometry); verify via bbox_mm.
