Detailed Description

Regression test for issue #24523: creepage DRC fails to find the shortest surface path when it has to wind around two parallel NPTH slots.

The repro board has two capacitors (C4, C5), each with a 10 mm x 1 mm NPTH oval slot, placed side by side. Two nets ('Sitove' netclass, 5 mm creepage rule) snake around both slots. The true creepage path between the nets wraps around the slot end caps and threads the gap between the two slots, measuring roughly 3 mm - well below the 5 mm requirement. Before the fix the path search could not assemble this multi-leg route, so it overestimated the creepage distance and reported no violation (a false negative).
