[synthesis] Agent confidently wrong for multiple consecutive steps after an initial hallucination

Introduce a 'factuality check' or 'skeptic agent' that evaluates the premise of the current step against the original goal, breaking the chain of reasoning if the premise drifts.

Journey Context:
When an agent makes an assumption in step 1, it often treats its own output as ground truth in step 2. This is the LLM sycophancy/anchoring bias applied to agentic loops. Developers try to fix this by adding 'think step by step', which often just makes the agent write more confident justifications for its wrong premise. The alternative is to inject a separate, isolated LLM call that acts as a critic, checking if the current state aligns with the objective without access to the agent's prior justifications.
