[architecture] Router agent sending tasks to the wrong specialist agent causing infinite handoff loops

Implement confidence thresholds on the router agent. If routing confidence is low, default to a generalist agent or prompt the user for clarification rather than forcing a handoff to a specialist.

Journey Context:
A critical failure mode in multi-agent systems is a router agent forcing a handoff to a poorly matched specialist. The specialist, unable to handle the task, hands it back to the router, creating a ping-pong loop that burns tokens. By requiring the router to output a confidence score \(or using an entropy threshold on the classifier\), you trap low-confidence routes. Routing to a safe, broad-competency generalist breaks the loop and preserves user experience.
