Erik b72851a3ee docs(phase-2): refine design after DatReaderWriter spike
Verified the real GfxObj data shape against DatReaderWriter's generated
types and WorldBuilder's ObjectMeshManager. Three corrections:

- GfxObj.Surfaces is a list and Polygon.PosSurface indexes into it;
  multiple surfaces per GfxObj are the norm. GfxObjMesh.Build now
  returns IReadOnlyList<GfxObjSubMesh> — one sub-mesh per referenced
  surface. StaticMeshRenderer draws entities by grouping entities by
  GfxObj and then by sub-mesh within each GfxObj. Matches the approach
  WorldBuilder takes.

- LandBlockInfo has both Objects (Stabs — small decorations, rocks,
  trees) AND Buildings (BuildingInfo). LandblockLoader loads both
  lists and maps them uniformly to WorldEntity since both types share
  the Frame shape.

- Stab.Frame and BuildingInfo.Frame carry position+orientation only,
  no scale component. WorldEntity.Scale dropped. WorldEntitySnapshot
  loses its Scale field too. Phase 3+ can add it back if needed.

Closes the one open design question flagged in the original doc.
