Phase 890: registry split + delivery receipt responder helper (v0.8.857)

Non-breaking refactor — split gossip-rpc-registry into entries/lookup/validate
modules; buildGuildRpcTargetedDeliveryReceiptResponse() shared by audit/digest
responders; platform-search-rpc-pull-mixin for search mesh config pulls. test:ci-phase890
passes (46/50, cutover deferred).
