feat(editor): add --gen-village-pack composite

Third composite pack (after --gen-camp-pack and
--gen-blacksmith-pack), emitting a 7-primitive village-square
scene into <outDir>:

  • house — main dwelling
  • outhouse — privy beside it
  • chimney — for the house roof piece
  • hitching-post — at the hitching rail
  • well — village square centerpiece
  • signpost — pointing the way out of town
  • haystack — from the nearby farm

Together these form a recognizable rural-village hub when
arranged in a zone. Uses the existing emitMeshPack helper —
the new pack is just an 8-line declarative table.

All 7 outputs validate clean (--validate-wom PASSED across
the board). Composite-pack catalogue now: camp + blacksmith
+ village.
