[synthesis] Agent loops idly in valid but dead-end FSM states without erroring out

Implement a 'state transition entropy' metric. If the agent oscillates between the same 2-3 states or stays in a non-terminal state for >K steps without state progression, force an exit or human escalation.

Journey Context:
Agent logic is often modeled as a state machine. A silent failure mode is reaching a state that is syntactically valid but logically a dead end for the specific user goal. The agent keeps querying the same data or asking the same clarifying questions because it has no path to the goal state. No exception is thrown because the state is valid. Monitoring must track progress \(state transition novelty\), not just validity.
