trace: Unreal timing traces run without hash capture (L71); verify baselines tracked

The L70 "2x SurfaceWorld GenerateTile in Unreal" was the instrument: the trace enabled
bCaptureVoxelForgeCoreHashesForValidation, which disables the native heightfield-band
shortcut and whole-tile skips (W1 same keys: 9.00 s hash-off vs 28.46 s hash-on). With
hashing off, Unreal and headless match at W8 within 1.2-2.5% (Core 14.42 s vs 14.26 s) on
identical tile keys. LOD0 p95 tail = real cost of non-empty passage tiles near the spawn mouth
(p50/p95 18.8/105 ms); most LOD0 tiles are empty.

verify.py reads its baselines from Standalone/Tools/verify/baselines/ instead of untracked
Saved/Linux. The 11 .vfmesh control meshes (~78 MB) are not committed yet (to be stored
compressed). Fast tier green.
