A directory's display: map (on-disk child name → friendly label) was read
only from the immediate on-disk .zddc, so the baked-in defaults could never
supply labels. Resolve it through the cascade instead (new zddc.DisplayAt:
embedded baseline + ancestor + on-disk overrides, deepest wins per key) and
declare the labels in the embedded project-level default
(defaults/_any_/.zddc):
archive→Archive, incoming→Incoming, working→Working, staging→Staging,
reviewing→Reviewing, mdl→"Master Deliverables List", rsk→"Risk Register",
ssr→"Supplier/Subcontractor Status Report".
On-disk names stay simple/lowercase; clients render display_name in their
place (browse already does). An operator's on-disk display: still wins per
key. Drops the now-unused readDisplayMap (folded into DisplayAt). Verified
in a containerized browser: /Proj/ shows all eight friendly labels, with
mdl/rsk/ssr still rendered as click-to-table leaves.
