refactor(prisma-next): consume @cipherstash/stack/adapter-kit, drop the eql/v3 graduation

The branch had graduated DOMAIN_REGISTRY / factoryForDomain /
stripDomainSchema onto the public eql/v3 barrel while adapter-kit still
exported the same symbols — two doors to one registry. Revert the
graduation and import through adapter-kit, the seam the Drizzle and
Supabase adapters already consume (PR #655 review, item 3). Also make
v3Authored return a fresh descriptor per invocation so a caller
mutation cannot alter later contracts (review).
