Erik 47f2cea1e8 test(N.5b): quantify WB vs retail terrain split formula divergence
Sweeps all (lbX, lbY, cellX, cellY) tuples for the full 255x255
landblock map (~4.16M cells) and reports both the raw enum-output
disagreement (50.02%) and the diagonal-actually-painted disagreement
(49.98%) between WB's CalculateSplitDirection and acdream's
TerrainBlending.CalculateSplitDirection (which retail uses per
CLandBlockStruct::ConstructPolygons at retail addr 00531d10).

The two formulas behave like independent random hashes. Adopting
WB's pipeline wholesale would mis-render ~half the diagonals on
every landblock (Holtburg 0xA9B0: 29/64 cells = 45.3% wrong). This
data is the foundation for N.5b's Path A vs B vs C decision (kills
Path A).
