Every Unity.Mathematics using, alias and qualified name under Assets\Scripts and tools now names CultMath. The nine `using static ...noise;` lines are gone: snoise lives on CultMath's math. UnityExtensions loses float4.ToColor and Color.ToFloat4, which duplicate the bridge's ToColor and ToCultMath; the float3 colour pair stays because the bridge has none.
