Closes deferred-work register item #14 with full fidelity. The Central UI Test-Run sandbox previously threw ScriptSandboxException for Attributes.WaitAsync/WaitForAsync; now the value-equality forms route to the bound deployed instance over the same cross-site path inbound Route.To().WaitForAttribute() uses. - Commons: additive trailing RouteToWaitForAttributeRequest.RequireGoodQuality (default false; message-evolution safe) so quality-gated waits route too. - SiteRuntime: DeploymentManagerActor's routed-wait handler now threads request.RequireGoodQuality into the InstanceActor WaitForAttributeRequest (previously hard-coded to default). - CentralUI sandbox: ISandboxInstanceGateway.WaitForAttributeAsync + SandboxInstanceGateway impl (via CommunicationService.RouteToWaitForAttributeAsync); SandboxAttributeAccessor value-equality WaitAsync/WaitForAsync route through it (codec-encoded target, scope-resolved name). Predicate overloads stay unsupported (an in-process lambda can't be routed) and throw a clearer, dedicated message. - Tests: sandbox accessor routing + predicate/unbound rejection (CentralUI); site-handler RequireGoodQuality threading (SiteRuntime). Register + the historical waitfor-deferred plan doc updated. Full slnx build 0/0; CentralUI 59, SiteRuntime routed-wait 4, InboundAPI wait 32 green.
