sda4: commit the Glaze developer hard-drive dump

Un-ignored: the dev drive is the ground truth the restoration and
emulator work constantly reference (DPL3/LIBDPL + VRENDER i860 renderer
source, BT/RP live+dev game trees, VGL_LABS pod boot, scene/audio
content). Kept in-repo for the pod-owner community.
