Function invert_periodic_surface_certified

pub fn invert_periodic_surface_certified(
    surface: &PeriodicBSplineSurface,
    point: DVec3,
    options: CertifiedSurfaceProjectionOptions,
) -> Result<Result<SurfaceInversionCertificate3, SurfaceInversionRefusal>, GeomError>

Globally invert a point against one canonical period of a cyclic surface.

The seam is searched as part of the quotient domain, so a point exactly ON the seam yields one enclosure rather than two rival endpoint boxes.
