[architecture] Router agent confidently sending tasks to the wrong specialized agent, causing cascading failures

Implement confidence-aware routing using embedding similarity or explicit LLM confidence thresholds, with a fallback to a generalist agent or human-in-the-loop when confidence is low.

Journey Context:
Using an LLM as a semantic router often results in overconfident misclassification. If the router sends a coding task to a billing agent, the billing agent will hallucinate a response rather than admitting it's the wrong agent. By forcing the router to output a confidence score, or by using a deterministic embedding-based semantic router, you can catch ambiguous queries. The tradeoff is that adding a confidence threshold might require manual tuning and occasionally route to the generalist when a specialist could have handled it, but it prevents catastrophic workflow derailment.
