[architecture] Router agent blindly dispatching tasks to the wrong specialist, causing cascading hallucinations

Implement confidence-aware routing with a fallback. If the router's confidence score for all specialists is below a threshold, route to a generalist agent or ask the user for clarification.

Journey Context:
Semantic routers often force a choice even when no agent is a good fit, leading to an agent trying to use tools it doesn't have or hallucinating capabilities. A 'none of the above' option is critical. The tradeoff is that lowering the confidence threshold increases fallbacks to the generalist \(which might be less capable\), but it prevents the catastrophic failure of an agent operating outside its domain.
