Thijs Damsma d3477d8996 surface.cone_p3: native guard for UB-154 seam-line intersections ...

- shim: replay IntersectWithCone / IntersectWithPlane up to the two seam
  smgu_LinePlaneIntersect calls of sm_GetEllipseTrimIntervals; refuse
  (SC_ERR_ARG) iff one fails (upstream then reads uninitialised dParam)
- ffi: document the guard; native test
  guards_ub154_only_when_a_seam_line_intersection_fails
- fixtures ub154.json: 7 rejections (issue #276 fuzz00656, fuzz09540,
  zero-height, 0.99e-12 seams), 13 compared neighbours just inside validity
