Make install + surface read the registry's derived profileMembership/
capabilityClusters so a capability's tier drives what installs + surfaces.
resolveProfile (when given the registry) unions capability skills for the
profiles its tier implies before the requires: closure; resolveSurface merges
capabilityClusters into the cluster map. bin/install.js, /gsd:surface, and the
capability-state resolver all thread the registry.
Shipped as a proven no-op: the UI capability is reconciled to tier:full (its
skills were full-only in the hand-authored profiles), so it contributes only to
the full profile (already the '*' sentinel) and core/standard are unchanged.
Equivalence tests prove resolveProfile/resolveSurface/listSurface/staging/
capability-state are identical with vs without the registry; the core-alias
staging path is verified equivalent (empty manifest → raw PROFILES.core).
