The GPU path tests (and the Windows FXC job, cargo test -p solidcraft-gpu) build real
designs through solidcraft-engine, a dev-dependency without its smlib feature. Run on
their own (-p solidcraft-gpu), nothing in the build turns SMLib on, so every geometric
step answered "this build has no SMLib" (10 path::* tests on develop). The
dev-dependency now asks for engine/smlib, as the apps do, and both jobs fetch SMLib
before building.
