      Anthropic.SDK 5.10.0 was compiled against Microsoft.Extensions.AI.Abstractions 10.3.0;
      the repo's central pin (10.5.0) reshapes HostedMcpServerTool.AuthorizationToken and
      causes a runtime MissingMethodException. Pin this throwaway harness to the SDK's
      compile-time targets via VersionOverride.
