[synthesis] Agent confidently executes wrong plan for multiple steps due to confirmation bias and plan lock-in

Inject a reflection and re-planning step after every N tool calls, explicitly prompting the agent to list evidence against its current plan before continuing.

Journey Context:
Standard ReAct loops ask 'What is the next step?', which biases the LLM to continue the current trajectory. Even if a tool output contradicts the premise, the LLM rationalizes it. Simply asking 'Did this work?' is insufficient; you must force the model to generate contradicting evidence. The tradeoff is higher token cost and slower execution, but it breaks the cascade of confidently wrong steps.
