jyvikoandClaude Opus 5.5 2456912850 mesh: strong relax objective never ranks an inverted element below a valid one ...

In the max-min phase a valid element's term q^-16 reached 1e96 as q -> 0+, far above
an invalid element's 2e8, so the descent kept elements inverted rather than pass
through flat: the distorted plate stayed tangled (4 invalid) once its mesh was the
same on every platform. The shape term now continues as its tangent line below
q = 0.3 (finite, steep) and an invalid element costs 1e11, above any valid one.

Adds a test that the plate's mesh, its perturbation and the strong relaxation are
the same bits with 1 and 4 threads and match a fingerprint taken on macOS (CI checks
it on Linux).

Part of #438.
