Requested by Nibu for a Voxel Space ring-buffer terrain. Adds PhacelleRowOrderTests: rows of math.phacelle samples (pure in world x, z and seed) are bit-identical generated forward, backward or shuffled, and after unrelated rows/seeds; a guard test shows rows do depend on seed and z. Golden fixture unchanged. 3 tests pass.

Pins that height rows built from math.phacelle (the C# mirror of cultmath_phacelle) are bit-identical
whatever order the rows are generated in, for a ring-buffer terrain. Golden fixture untouched.
