Build each kind without MakeNurb in the shim and in Rust, run the const natural-domain
query that makes the NURB lazily, then point/normal evaluations at the domain corners,
Copy, == and Transform, comparing has-NURB, the NURB data and evaluations. Cases cover
swap/inside-out, partial domains, sphere caps ending at a pole, a torus with minor radius
equal to and above the major radius, and revolutions about an axis touched or crossed by
the generator.

SmSphere and SmTorus inherit SmSurfOfRevolution::TrimWithDomain; its
virtual ConvertUVFromNURBSToSTEP (UpdateAnalyticalDomain) and
CreateIsoParametricCurve (MakeNurb, Reparameterize, RebuildPolarConverter)
now reach the sphere/torus overrides through trim_with_domain_using, and
SurfaceKind::Sphere/Torus dispatch to it instead of a dispatch gap.
surface.sphere and surface.torus difftest a TrimDomain op.

Adds the three helpers to sc_sm.h, copied from the per-shim copies they
replace, and switches 19 shims to the shared flg/put_mat/put_vec/put_ivl/st/
put_dom. Shims touched by open PRs are left alone.

Add the surface.sphere difftest runner (800 generated cases, 0 deferred,
--perturb 800/800), C++ shim and FFI binding. Wire Sphere::read_from_db into
Surface::read_from_db and the ssi engine deferral, clamp the sqrt in
circle_radius, and point read_from_db_unported_types at the still-unported
offset surface type. plan/modules.toml: surface.sphere green.
