[architecture] Agent router sending tasks to the wrong specialist causing infinite handoff loops

Implement confidence-aware routing with a threshold; if confidence is below the threshold, route to a generalist agent or trigger human clarification rather than forcing a specialized agent choice.

Journey Context:
Standard zero-shot routing forces an LLM to classify an input into a fixed set of agents. If the input is ambiguous, the router guesses wrong. The specialized agent receives a task it can't handle, tries to use its tools, fails, and hands it back to the router, creating an infinite loop. Adding a 'none of the above' or low-confidence fallback breaks the cycle. The tradeoff is occasionally routing to a less optimal generalist, but it prevents system hangs.
