feat(editor): add --regen-collision CLI for batch WOC rebuild

Browse source 
Walks a zone directory recursively, finds every WHM file, and
rebuilds the matching WOC. Useful after batch terrain edits when
you want to refresh collision for many tiles in one shot. Reports
per-tile triangle counts and exits 1 if any rebuild failed.
