Speed up make check ~5x

Geometry constraint tests: replace full powerset (127 subsets of 7
geometry types) with singletons + pairs + full set (29 subsets).
GeometryTypeConstraint is a set-membership check — combinatorial
testing beyond pairs exercises no additional code paths.

Makefile: run pytest, doctest, ruff, and mypy concurrently via
make -j after a single upfront uv-sync. Added -only variants
(no uv-sync dep) for the parallel invocation; standalone targets
preserved with their original uv-sync dependencies.
