docs(render): AD-117 item 1 retired — the render-only destination-cell move is retail's own zero-sphere find_cell_list

Browse source 
CObjCell::find_cell_list (0x0052b4e0) with num_sphere == 0 adds only the
current cell — interior CELLARRAY::add_cell at 0x0052b563, outdoor
CLandCell::add_all_outside_cells (0x00533630, the arg2 <= 0 branch:
adjust_to_outside + gid_to_lcoord + add_outside_cell) — and skips the
portal transit walk (`arg4 != 0 && arg2 != 0` at 0x0052b576). So a shapeless
object's transition cell array is its destination cell alone, exactly what
RefreshPositionRows publishes. Not an adaptation; the register row keeps
its three residual readings, the S3 packet drops the capture request, and
the registry/test comments cite the verified function.
