## Title

    Reporter workaround: cancel RunAsync token after transport completion

## Body

    Source-backed, not verified by KFA: the issue reporter says they ship this host-side mitigation because the SDK handler for subscriptions/listen only completes on cancellation. It lets the last reply flush before cancelling. It is a workaround, not a confirmed fix or released change; no maintainer confirmation was supplied. See https://github.com/modelcontextprotocol/csharp-sdk/issues/1914.
