feat(editor): add --bake-wob-collision multi-group WOB→WOC

Browse source 
Sibling of --bake-wom-collision for buildings. Walks every
group in a WOB, optionally welds vertices PER GROUP (groups
are intentionally separate — rooms with portals between them,
so welding across groups would fuse walls that should remain
distinct collision surfaces), and appends each to a single
WoweeCollision via WoweeCollisionBuilder::addMesh.

Same flag surface as the WOM variant: optional [out.woc]
output path, --weld <eps> for per-group vertex merge,
--steep <deg> for the walkable/steep slope cutoff.

Smoke tested on a 1-group cube WOB: 8 verts → 12-triangle
WOC with proper bounds (-1,-1,-1)..(1,1,1) and walkable/
steep classification matching the cube face orientations.
