The vendored MIConvexHull (NIH, ported from double to float) returned triangulations that left whole sets of
interior zones with no cell at all (prelude seed 103: 22 of 64 zones; main seed 4247651650: 182 of 196). Those
zones had no link, Distance lacked them, and the constructor threw KeyNotFoundException placing the antagonist
home (prelude) or the entrance (main). Galaxy was its only consumer; Delaunay.Edges (Bowyer-Watson, double) replaces
it, and the 3,896 vendored lines go.
The three RestoredHullsTests loops that skipped seeds whose galaxy threw now require every seed to build, and the
stale comment that Galaxy mutates Faction.InfluenceDistance goes with them.
