Adom Step2GLB - STEP to GLB converter

#!/usr/bin/env bash
# step2glb ralph-loop test
# Pass criteria per package (all four must hold):
#   - ok: true
#   - meshes >= 1
#   - materials.length >= 1   (the "not all white" criterion — guards against regressing to cadquery default export)
#   - sizeBytes > 1000        (non-trivial geometry)
# Overall: 5/5 packages pass.
