Detailed Description

Creepage DRC test with HV/GND netclass constraints.

The board has an HV trace running near a GND trace. The custom rule requires 8mm creepage between HV and GND netclasses, but the actual surface distance is ~3.25mm.

A rule area has no net, so it lands on netcode 0 and used to be collected as copper. The netless corner tracks give netcode 0 a bounding box wide enough to get past the early reject in testCreepage. They sit too far from the HV track to violate anything.

Regression test for https://gitlab.com/kicad/code/kicad/-/issues/23653.

A board with an extra line on Edge.Cuts that prevents GetBoardPolygonOutlines from forming a valid polygon should still produce creepage violations. Previously the creepage test bailed out entirely when the outline was malformed.
