Add a gear-vs-body fit report to the Blender asset tool

`blender_assets.py fit` measures each character head width (skin vertices
weighted to Head in y 1.55-1.81) and clothing radius (cloth skirt in y 0.30-0.52,
pants hip fallback), then prints every attached head/back/chest gear bounding box
with head-band status and x/radial skirt clearance. The report confirms the
glasses width and shoulder-bag coat clip, giving the next fit fixes numbers.
Python tooling 87/87; asset audit clean.

+- Gear fit is measured with `python3 tools/blender_assets.py fit` (stdlib, reads the GLBs):
+  head width uses skin vertices weighted to Head in y 1.55–1.81; clothing radius is the cloth
+  skirt in y 0.30–0.52 with a pants hip fallback. The command reports per-character gear boxes,
+  head-band status and x/radial skirt clearance; `test_blender_assets` covers its shape.
