[architecture] Router agent confidently sends a task to the wrong specialist agent, causing cascading failures

Require the router to output a confidence score alongside the routing decision; if confidence is below a threshold, route to a generalist agent or prompt the user for clarification.

Journey Context:
Semantic routers often map a user query to an agent based on embedding similarity or LLM classification. These classifiers are notoriously miscalibrated and will confidently route a complex coding task to a simple documentation agent. Adding a confidence threshold with a fallback prevents the specialist from floundering or hallucinating outside its domain. The tradeoff is that low-confidence fallbacks to a generalist might result in slightly sub-optimal performance for edge cases, but it prevents catastrophic routing failures where a specialized agent operates completely out of scope.
