fix: correct lead-in approach angle formula mirroring pierce point

Browse Source 
The offset direction (start→pierce) is reversed from the approach
direction (pierce→start), so the old formula produced 180°−angle
instead of the requested angle. Invisible at the 90° default but
caused 45° to render as 135°.
