d88_emit.py appends the 21 Usetup*Z stage-setup files (object placement, AI
scripts, pads/nav) to the same data/pccg-<region>/ sidecar d69 produces.
Without it the port has no setup data for any level and segfaults on load
before frame 1 (this was mis-filed as D185 'd69 regression' — it was a
missing pipeline step). Vendor d88_emit.py + its one local import
d88_propdefs.py; run d43 -> d69 -> d88 --regen.
Verified: fresh d43+d69+d88 from an assembled bundle produces pccg.bin
(3604378 B, 74 rows) and pcmodels.bin byte-identical to the known-good
sidecars; -level_09 and -level_20 boot crash-free against them.
