feat(render) Campaign FW3.2b-2: THE STATIC CUTOVER - the walk drives production statics

The retail frame walk now drives every production static draw. In
RetailPViewRenderer.DrawInside, when the concrete executor + the
packed product + the FW3.1 walk registries are all wired (all
production compositions - anything less throws):

- A pre-walk events-only collection pass (the shadow sink generalized
  to WalkVisitedSetCollector) gathers the frame's visited cells,
  buildings, and landscape-cell turns; the visited cells union into
  prepareCells so EnvCellRenderer prepares every shell the driver
  draws.
- DrawWalkDrivenStatics runs the WalkFrameDriver over the production
  world data (WalkProductionWorldData over RenderSceneQuery + the
  building registry): sky, terrain slices, outdoor statics at their
  landscape-cell turns, buildings (alpha barrier -> punch/look-in
  passes -> shell) in retail order, interior clear+seals as leaf
  closures (the old tail block's drain reasoning moves with them),
  flood cells shell-then-contents. Landscape/cell-stage particle
  owners re-source from the walk's visited sets - retail gates
  particles per cell turn (ShouldDrawParticles @0x0050FE60), which
  this is; the old sphere filter was the approximation.
- DrawLandscapeDynamicsPhase + DrawBuildingLookInDynamics carry the
  dynamics-only remainder (LookInObject now dynamic-classified,
  late outside-dynamics + weather, particle unions); DrawDynamicsLast
  and the outdoor flush are unchanged.
- The product builder stops emitting LandscapeOutdoorStatic /
  LandscapeBuildingShell / CellStatic (methods deleted, dead index
  tracking removed); LookInObject loads cells with
  includeStatics: false.

The old static path survives ONLY behind !walkActive for the
standalone/diagnostic executor-fake path that keeps 15 retail-ordering
regression tests exercising the barrier/punch/seal machinery; no
production composition can reach it. Its deletion is FW4 scope (the
plan's "deleting the patch apparatus") - recorded in the plan.

Transitional risks recorded in code/report: the two-pass walk cost
(FW3.4 measures), the interior slice-count reconciliation between the
old clip assembly and the walk's own exit-view survival, and the
outdoor merged-flood punch coverage now riding the walk's own
building-BSP punches (retail-faithful per FW1; the owner visual gate
verifies).

Suites (lead-verified): full Release build 0 warnings; hermetic
6,750/0 (baseline minus the three deleted route tests); Walk lane
201/1; InstalledDat Walk conformance 40/1 untouched. The two
IL-branch tests the implementation round reported failing pass in
every lead run - the recurring parallel-load flake pair.

+- **FW3.2b-2 — the production rooting (DESIGN, 2026-08-30; execute
+  INLINE, not via subagent — the integration-slice rule).** The
+  dual-compute split for this stage: the OLD visibility
+  (`PortalVisibilityBuilder` + look-in frames + clip assembly +
+  viewcone) KEEPS RUNNING to feed everything dynamic; the WALK draws
+  everything static. No old static DRAWS remain (no double draw):
+  1. `RetailPViewRenderer.DrawInside` keeps steps 1–8 and 10–11
+     (visibility, merge/look-in seeding, clip frame, prepare — with
+     `prepareCells` UNIONED with the walk's flood/look-in cells —
+     viewcone, route build) but `RenderScenePViewFrameProduct` STOPS
+     emitting `LandscapeOutdoorStatic`, `LandscapeBuildingShell`, and
+     `CellStatic` ranges. Per the plan's route split, LOOK-IN OBJECTS
+     (`LookInObject`) are dynamic-side and STAY PACKED this stage —
+     the old look-in machinery keeps drawing look-in cell content and
+     its punches; the WALK's building turns therefore draw shell
+     content + punches for NON-look-in... NO — resolve the overlap the
+     other way: the walk's building turns run their punch+look-in
+     machinery ONLY for the walk's own conformance events; production
+     look-in DRAWS (punch fans + content) stay entirely on the old
+     path this stage, and the walk's `BuildingShell` stage content +
+     `OnPunchGeometry`/look-in DC draws are SUPPRESSED in the driver's
+     production wiring for look-in-owned buildings… REJECTED — that is
+     a dual path. FINAL: the walk owns ALL of it — building shells,
+     punches, look-in STATIC content (stage LookInStatic) — and the
+     `LookInObject` route survives ONLY for the DYNAMICS inside
+     look-in cells (`BuildLookInRoutes` filtered to dynamic
+     classifications). The old `DrawBuildingLookIns` static half and
+     `DrawLookInPortalPunch` retire with the static routes.
+  2. `WalkFrameDriver`'s leaf renderer maps to:
+     sky → `RetailPViewPassExecutor` sky call; terrain slice →
+     `_terrain.Draw(camera, frustum, clipPlanes: slice.Planes,
+     ndcClipAabb: slice.NdcAabb)`; cell shell →
+     `EnvCellRenderer.Render(pass, singleCellSet)` (+ transparent
+     ordered per cell); punch fan → `PortalDepthMaskRenderer.
+     DrawDepthFan(worldVerts, viewProjection, slicePlanes,
+     forceFarZ: true)`; `ClearInteriorDepth` →
+     `IWorldPassScope.ClearInteriorDepth` (keep production's
+     slices>0 gate); `DrawExitSeals` → the existing seal-fan loop
+     (`DrawPortalDepthWrite` seal flavor over the root flood's exit
+     portals); alpha barrier → `RetailAlphaQueue.FlushFartherThan`.
+  3. Static records: cell statics via `RenderSceneQuery.
+     CopyCellStaticsTo(cellId)`; outdoor statics via a per-landscape-
+     cell index built once per frame from
+     `CopyIndexTo(OutdoorStatic)`; building shells via the
+     `IsBuildingShell` entities keyed by anchor cell.
+  4. Consumers re-pointed: particle owners
+     (`RenderFrameRouteOwnerSelector.Replace(LandscapeOutdoorStatic…)`
+     sites) re-source from the walk's populated cells; diagnostics
+     source counts tolerate the route removal; `EmitRenderSignature`'s
+     terrain/scenery counts re-source or annotate.
+  5. Sky/weather: sky moves into the walk's LS turn (once); weather
+     stays in the old late-dynamics slice loop this stage (it is
+     dynamic-adjacent and the plan's FW4 moves it fully).
+  6. Gates before the owner sees a build: hermetic + InstalledDat
+     suites; the connected lifecycle route; the offline pixel gate
+     (outdoor statics); dense-Arwic pre/post pair (physical display).
