[synthesis] Agent outputs a plausible but incorrect final answer instead of admitting uncertainty, masking task failure as success

Implement a calibrated confidence threshold and a dedicated 'abort/uncertain' tool, tracking the ratio of uncertain exits to total tasks.

Journey Context:
Agents are typically designed to output a final answer. When an agent hits a dead end \(e.g., cannot find the bug\), it rarely outputs 'I failed'. Instead, it generates a highly plausible but incorrect answer. Monitoring sees a 100% task completion rate, leading teams to believe the agent is working perfectly, while actual utility is zero. Giving the agent an explicit, reward-optimized 'I don't know' exit path allows it to fail gracefully and provides true visibility into agent limitations.
