feat(render) Campaign FW1: the landscape replay world + first outdoor diff

Browse source 
WalkLandscapeDatBuilder assembles the replay grid with the LIVE-dumped
retail landscape model (LScape mid_radius=25 -> 51x51; the resolution
pyramid observed on the capture client: side_cell_count 8 in the 3x3
core, 4 at ring 2, 2 at rings 3-4, 1 beyond; buildings attach only to
full-res blocks - matching the traces roster), retail z-slabs
(heightTable[max]+200 / [min]-1 per CLandBlock unpack @0052f297), and
camera-block-local coordinates. The replay context gains the building
half (placements, active-view install, building-polygon clip). The
street-outdoor conformance diff now reaches real adjudication: the walk
over-culls six traced buildings (jagged boundary - not a clean frustum
edge) and the look-in floods differ; the driving test is parked Skip
while the visibility map is instrumented.
