CultMath's hash(float2) returns float, not uint, so ZoneGenerator folds its
bits into the zone seed with BitConverter.SingleToInt32Bits. MathResolver's
int2?[] entry used ArrayFormatter<float2?>; it now uses ArrayFormatter<int2?>.
Aetheria.Shared and AetherDb build headless with 0 errors, and AetherDb's
census, factions and hardpoint-fit output is byte-identical to the captures
taken before the swap.
