Cumulative PR layer #4847. Installs the reviewed provider-neutral relay authorization runtime, crash-recoverable current-status delivery, protected-ingress production composition, canonical mutation ordering, and exact runtime-contract regressions. A configured required identity gate remains fail-closed when its retired compatibility verifier is unavailable.
Neighbor disclosure: canonical database/operator authority remains owned by the lower layers, while the core status contract is owned by #4790 and native desktop consumption remains in #4987.
