[architecture] Router agent dispatches tasks to specialized agents with low confidence, causing cascading hallucinations or infinite handoff loops

Implement confidence-aware routing with a fallback and a strict max-handoff counter. If intent matching confidence is low, route to a generalist or back to the user.

Journey Context:
A common failure mode is the ping-pong effect, where Agent A hands off to Agent B, who hands back because neither is confident. LLMs try to be helpful even lacking context. By requiring confidence thresholds and enforcing max\_handoffs, you prevent infinite loops. Tradeoff: May prematurely abort a task that could have been resolved with more context, but saves massive token burn and latency.
