+- Extended the `cancel_on_interruption=False` regression fix to `InworldRealtimeLLMService`. Uses the same approach as in #4441 (the service detects async-tool messages in the LLM context and routes the final result to its formal tool-result channel). Note: as of this writing, Inworld Realtime doesn't appear to handle the resulting delayed tool result reliably — the routing is best-effort and the service surfaces a one-time warning when async-tool messages are seen. Streamed intermediate results (`FunctionCallResultProperties(is_final=False)`) are still not supported on this realtime service. (Inworld was excluded from #4447 pending resolution of an unrelated tool-calling issue, which turned out to be an account-level matter.)
