feat(editor): add --bake-zone-collision aggregator

Browse Source 
Walks every .wom and .wob under <zoneDir>, optionally welds
each one independently (per-mesh / per-WOB-group), and
appends its triangles to a single WoweeCollision. Useful for
shipping a zone — one .woc artifact holds all object collision
so the server side has just one file to load.

Per-file weld preserves between-object boundaries: two
distinct WOMs sitting at the same world position keep
their topology separate even if their corner positions
happen to overlap.

Same flag surface as the single-file bakers: optional
[out.woc] (defaults to <zoneDir>/zone.woc), --weld <eps>,
--steep <deg> for the walkable/steep slope cutoff.

Smoke tested over /tmp/migtest: scanned 79 WOM + 1 WOB,
produced 9259-triangle WOC (1563 walkable, 1943 steep)
with correct world bounds.
