FIX24 — CUMULATIVE TEXCOORD2 TEST

Base: uploaded FIX23 / cumulative FIX22 state.

Preserved: all existing geometry, Texcoord 20→28 conversion, hashes, Blend/DRAW_TYPE structure, cumulative BodyPosition changes, IB, DDS, Hair and resources.

Two concrete corrections were made:
1. Corrected stale Body draw counts in merged.ini: swapvar 0 = 172819 and swapvar 5 = 173019, matching the actual BodyPosition/IB vertex limits.
2. FIX23 had a defect: its TEXCOORD2 neutralization was not actually applied to Body variant 0. This version sets TEXCOORD2.xy = (0,0) in all seven BodyTexcoord buffers.

No UV0/TEXCOORD, TEXCOORD1, VColor, Position, Blend, IB or textures were changed.

Purpose: this is the first valid test of the hypothesis that TEXCOORD2 is involved. If the lower-body patches remain identical, TEXCOORD2 can be discarded as the cause and the next target is specifically TEXCOORD/UV0 correspondence, while retaining this cumulative base.
