Erik c94a1a407e feat(render): Campaign OVERHAUL S2 chunk 5 + closeout — registry is the only render membership owner
Chunk 5 (consumer cutover): WalkProductionWorldData's per-cell views are
borrowed from ShadowObjectRegistry.GetRetailPartEntriesInCell and resolved
through RenderSceneQuery.TryGetByLocalEntityId; every render-side sweep,
bucket, parent-cell and root-position fallback is deleted (AD-116 for the
one-frame registry→scene window, counted in UnregisteredRenderMembershipCount).
A live entity with visual parts but no collision geometry registers
render-only (LiveEntityCollisionBuilder computes the part array before the
empty-shapes gate).

Closeout fixes found while landing it:
- RefloodOwnerForLandblock forwards the retained part array — a reflood is
  retail's recalc_cross_cells over the SAME CPartArray; without it every owner
  touched by a landblock replacement commit lost its render membership.
- Non-colliding DAT statics register render-only from BOTH publishers
  (LandblockPhysicsPublisher.PublishStaticEntity,
  LandblockPhysicsContentBuilder.RegisterRenderOnlyStatic). The G2 self-gate
  pixel diff caught them vanishing (Facility Hub wall panels): retail floods
  every object regardless of collision (CEnvCell::init_static_objects
  0x0052c350, add_shadows_to_cells 0x00514ae0).
- S2 dual review fix batch (arch + retail lens, lead-verified):
  Suspend clears the retail product (remove_shadows_from_cells 0x00511230 is
  one transaction); AttachChild/DetachChild advance the mutation revision so
  a prepared SetPosition cannot clobber a child's rows; an attached child
  never floods on its own re-registration; RemoveLandblock and the non-rooted
  RetireOwnerFromLandblock prune retail rows (render-only statics end with
  their landblock); a render-only owner's no-cell-array commit republishes at
  its destination cell (AD-117); an empty non-null part array is treated as
  null; per-move closures/LINQ replaced by index loops; EnvCell shells stay
  out of the scene's LocalEntityId index (payload-less records); the index
  predicate compares the id; the dead per-cell scene indices are deleted.

Register: AD-116 (chunk 5), AD-117 (four residual Contract A/B readings).
Evidence: s2-membership-ownership-map.md §8 (chunk 5) and §9 (closeout).
