Add missing sweep edges for open surface extrudes

[pierremtb]

Codex did pretty good plumbing work here to get the previous adjacent edge at the start of each open profile component. It maps these artifacts to getPreviousAdjacentEdge(...), allowing point-and-click extrusion to use it and avoid falling back to edgeId. There's a single open single-segment surface extrusion case.

Likely not needed after #11727 but could be a good interim fix?

Rescoped after reporting the missing edge from GetAdjacencyInfo https://github.com/KittyCAD/engine/issues/4785, now that it's live we can simply do the plumbing bits, no need for a frontend patch anymore!

Allows extruding all four edges from a segment-extrude like this without falling back to faceId, as found in #12018 (review)

@settings(kclVersion = 2.0)

sketch001 = sketch(on = XZ) {
  line1 = line(start = [var -2.2mm, var 0.4mm], end = [var 3.48mm, var 1.03mm])
}
extrude001 = extrude(sketch001.line1, length = 5, bodyType = SURFACE)

Footnotes

1. 151 benchmarks were skipped, so the baseline results were used instead. If they were deleted from the codebase, click here and archive them to remove them from the performance reports. ↩

2. No successful run was found on main (ab76678) during the generation of this report, so 50d506e was used instead as the comparison base. There might be some changes unrelated to this pull request in this report. ↩

I don't really understand why we update all these, but it's what we do for Solid3dGetAdjacencyInfo, so it's probably fine.
