jyvikoandClaude Opus 5.5 c6eeac35c1 solver: a node in several ties gets one constraint; ties both ways are an error (#389) ...

A node on the secondary surfaces of two ties (a chip's underside and its
sides, a cut face and an outer face) got one constraint per tie. When the
main nodes of one follow the other's main surface, the second constraint is
nearly the first again, and eliminating it divided by round-off: the Pi 5
heat model put 21.9 W more in than its 8 W. Such a node now follows the
main faces of all its ties together (balanced to 5e-11 of the power), a
node following a node that follows it back (a tie each way on one
interface) is an error naming both ties, and a tie row that still nearly
repeats the constraints before it is an error naming them.

mesh.cells ties one way by a fixed order of the cells (hex main to tet)
and makes one tie per tied cell, tie_<cell>, replacing the ties an earlier
run made, so its own ties never hold a node twice.
