feat(render) Campaign FW1: FIRST TRACE CONFORMANCE GREEN (foundry-deep)

Browse source 
The replay harness reconstructs the camera from a pose-stamped oracle
frame (Frame quaternion w,x,y,z storage order; +Y forward / +Z up;
landblock-local origin) and drives the ported walk over adapter-built
cells (cell transforms from EnvCell.Position now populated). The
foundry-deep fixture - the pure-interior frame shape - reproduces
retail EXACTLY on every complete frame: DI + DC(ov=0, [cell]) with no
landscape, 39/39. Conventions are now pinned by live retail output; the
remaining nine fixtures need the outdoor world build-out (landscape
blocks, terrain z-slabs, building transforms + active-view clip) and
join the same gate.
