The registry listed 20 synthetic /Game/Ralpha/MetaHumans/... entries with no
on-disk asset and omitted the real spawnable BPs, so packaged-runtime
spawn_metahuman (which can't scan — scan is editor-only) would fail. Regenerated
to the 2 BPs that actually exist: MH_Aera -> /Game/MetaHumans/Aera_MHC/BP_Aera,
MH_Cen -> /Game/MetaHumans/Cen/BP_Cen.
Found by proper-review-v2 round-1 ping-pong (Codex). Source of truth:
ralpha/scripts/dev/regen_metahuman_registry.py (filesystem scan, no editor).
