125 shims carried private copies of the same small helpers (put_vec, st,
nl_status, Rd, dump_crv, read_nurb, ...). Move the most common, byte-identical
form of each into three headers grouped by the upstream API they need, and have
those shims pull them in with `using sc::<name>;`. Shims with a different
variant keep their own copy; files touched by open PRs are left alone.
`the_context()` stays per shim (its function-local SmContext must not be shared).

Plane fallback line interval, InvertPointNearSingularity tolerance and
DropPoint result, sm_ExtractIsoCurve tolerance, ignored statuses
(GlobalCurveIntersect combine, SpLocal add, CreateBlendSurface,
coincidence evaluations with only_upper_half), non-zero tangents in
sm_IntersectSrfBndryCrv, GlobalPointSolve_0 wired with the kernel and the
surface handle, UB-116 -> UB-119 and HANG-14 -> HANG-15, volume_p1 and the
units whose surface_p8 deferrals are gone promoted to green.

SubdivideToTolerances refuses to split past MAX_SUBDIVISION_NODES (2^18) tree nodes:
an extreme-scale surface was split into millions of Bezier patches and Rust aborted
on a 3.5 GB allocation while generating surface.surface_p7 solve cases. The p7
generator checks the other surface's scale too; the shim's put_sols takes a
non-const array.

GlobalCurveSolve/GlobalSurfaceSolve difftest cases now compare the first 16 solutions
(type, value, parameters), not only their count; the p7 generator adds normalize and
signed directed curve solves and generated surface/surface solves (a patch lifted clear
above the surface; intersect for node pairs). The generator checks the scale before the
Rust run (which now runs the solve). CsGlobalSolver::BranchMayContainAnswers uses the
solve cache's polar boxes.

Checklist (AGENTS.md section 4.5): SmPlane::IsClosed is plane_p1's (ported),
not a plane_p2 stub; CreateParallelProjectionCurves keeps its approximation
and angle tolerances; no UNPORTED tag for the partial surface_cache_p1; the
FFI accepts any finite IsClosed/IsPlanar tolerance; the shim builds
curve-bounded surfaces; the generator adds 1e-4/1e4 scales and keeps the
always-deferred global solves at unit scale (GlobalSurfaceSolve is
fixture-only: intersecting surfaces take upstream minutes).
difftest: 3658 cases, 3029 pass bit-identical, 0 fail, 629 deferred.
Upstream issues UB-73, WR-48..50. Unit tests that asserted the old stubs now
check the wired results. Reports of the touched units regenerated.
