feat(editor): add --build-woc CLI for headless collision generation

Browse source 
Loads a WHM/WOT terrain pair and writes a .woc collision mesh
alongside it. Terrain triangles only (no WMO overlays — those need
the asset manager) but enough for first-pass walkability while
authoring.

Verified end-to-end: scaffold-zone → build-woc → info-woc reports
32k triangles for a flat 256-chunk tile.
