#921's grid lines through the vertices that split a ruling edge also went into the meshes Boolean operations intersect, which changed seven robustness seeds (seed 2's sphere cut failed). Deflection::rulings now asks for them only in the kernel's own tessellation (display, export, measurement). The seeds #936 (rejected instead of unsupported), #946 (26 and 85 build, others fail differently) and #921's display side (about 1e-6) moved are recorded with their reasons.

Rolling-ball blends now handle knife edges, where the two faces have opposite normals; an edge that runs out along an end face tangent to one side; and rounds that end in an earlier round on curved faces, picked together or one after another. The three edges at a vertex of smooth faces, rounded to one radius, end in a piece of sphere. When the given order of up to four edges is refused, or leaves a face boundary off its surface, other orders are tried.
Closes#851.

* Fillet and chamfer: refuse a smooth seam as having no corner to round
Picking the seams where R10 rounds run into the faces beside them, and asking for an R1
fillet there, failed with "not supported yet: blending a smooth edge (... both faces next
to the edge must be planar)". That reads like a missing feature, but the faces meet
tangentially at those edges and there is nothing to round.
An edge whose two faces are tangent along it is now refused as an invalid pick that names
the edge and asks for the sharp edges.
Fixes#896.

* Robustness goldens: seed 72's smooth-seam fillet is now a rejected pick, not unsupported

Main has failed the full robustness goldens since #838, #839, #841, #855 and #856 landed together. Records the eleven seeds that now build differently (2, 6, 14, 22, 36, 43, 50, 63, 71, 73, 94), with a note. Shell now refusing seed 14, which used to build, is tracked in #897.
tests/robustness/goldens.json records what each of seeds 0-95 builds: its steps, how it ended (ok, or the kind and the start of the error it was refused with) and, for the design it left, the bodies' total volume and area (within a relative 1e-6) and their face, edge and shell counts. tests::robustness_goldens fails on any change; ROBUSTNESS_GOLDENS_BLESS="why" records one, with the reason and the seeds it moved. Pull requests that touch crates/kernel run every 8th seed; pushes to main and the nightly run every seed.
