feat(render): S2 chunk 2 - render statics borrow the registry's retail cell array

WalkProductionWorldData no longer floods; its indoor and outdoor static
sweeps read ShadowObjectRegistry.TryGetRetailCellArray (retail's
calc_cross_cells_static @0x00515160 -> AddPartsShadow @0x00517e40
CELLARRAY, computed once at registration). The App-owned render flood
(ResolveStaticRenderCells, its fingerprint cache, the primitive-Setup
special case) and Core's ComputeStaticRenderCells are deleted. The one
remaining fallback, an entity the physics publisher has not registered yet
while the projection journal already published it, buckets to the authored
parent cell and is counted per frame (UnregisteredStaticRenderFallbackCount)
for chunk 5 to judge on the connected route.

The Facility stair pin now registers at the projection's own entity id
(the old pure-function test never carried identity) and reads the retail
array; the installed-DAT comparator compares retail against collision.

Gates (run in the implementer's isolated worktree at identical content):
Release build 0/0; Core Physics 2,202/2,202; App hermetic 6,760/6,760 (the
two added WalkProductionWorldData tests); installed-DAT walk/flood/stair
family 24/24; Runtime 1,884/1,884.
