Add interop test agent
The new stack-pass ObjectMethodProxyGenerator emits proxies that derive
from Opc.Ua.ObjectTypeClient and reference Session.MessageContext.NamespaceUris.
Neither type exists in the in-memory test compilation, which only references
Opc.Ua.Types.dll. Moving ObjectTypeClient to Opc.Ua.Types would cascade ISessionClient,
IClientBase, ITransportChannel and the generated service interfaces with it, so the
type stays in Opc.Ua.Core and we add a minimal stub to OpcUaCoreStubs instead.
Wire Microsoft.Extensions.Options 10.0.5 + DependencyInjection.Abstractions 10.0.5 into Directory.Packages.props and the Gds.Client.Common project to enable upcoming options-driven configuration work.
Modernize Opc.Ua.Gds.Client.Common (DI, options, interfaces, async dispose)
