feat(physics): S2 chunk 1b - callers supply the visual part array; installed-DAT comparator

Browse source 
Every production registration now hands ShadowObjectRegistry the object's
whole visual part array beside its collision dispatch: static publication
(App LandblockPhysicsPublisher and the headless Content twin) through
ShadowShapeBuilder.FromStaticRenderParts, live entities (Runtime
LiveEntityCollisionBuilder) through the new FromSetupRenderParts, which walks
every Setup part with the same physics-sphere-else-drawing-sphere and
part-box rule from the PhysicsDataCache Runtime already reaches. Nothing
consumes the retail products yet; the App hermetic lane still passes
6,758/6,758.

The Lane=InstalledDat comparator registers five real fixtures through the
real publication inputs and prints retail CELLARRAY, collision cells, and
the old render cells side by side: Facility Hub stair Setup 0x02000623
(7 cells incl. 0x8A02015F/015E), cathedral ramp 0x020009A2 (3 cells, the
genuine multi-part case), the #334 Neftet formation (25 cells), and a
landblock-edge crosser (6 cells, 2 in the neighbor block). All three
answers agree for BSP-bearing objects, as the shared primitive predicts;
the divergence chunk 3 expects appears only for decorative non-BSP parts.

Core Physics 2,202/2,202; Runtime 1,884/1,884; App hermetic 6,758/6,758;
comparator + stair pin 5/5; solution Release build 0 warnings / 0 errors.
