[architecture] Routing tasks to specialized agents without a fallback when the agent fails or hallucinates

Implement confidence-aware routing where a supervisor evaluates the worker agent's output and routes to a fallback generalist or human if validation fails.

Journey Context:
Developers route tasks to specialized agents assuming they will succeed. However, specialized agents often fail on edge cases outside their narrow system prompt, producing hallucinated tool calls or fabricated answers. A supervisor must check the result via a deterministic validator or a lightweight LLM call, and route to a generalist or retry if the output lacks confidence or violates constraints.
