Move the shoulder bag clear of coat and dress skirts

Narrow the bag to 0.06 m and move it outboard to centre x=0.292. The body inner
face is now 0.262 m, clearing the coat skirt (0.225) and dress (0.260); the
strap lower points start on the same line. The fit report measures the bag body
separately from the torso strap and uses a signed inner-face clearance. Run
Blender build/bake and Godot import. Python tooling 87/87.
