Subject: [PATCH] feat(editor): collectWMOTextures recurses into WMO doodad M2
 textures

WMO buildings reference M2 doodads (chairs, candles, banners) via the
MODD chunk. Their textures live in those M2 files, not the WMO root.
Now collectWMOTextures walks every doodad name and collects M2 textures
recursively so exported buildings include all their interior decoration
textures.
