[synthesis] Agent compounds errors across steps due to unverified intermediate assumptions becoming 'facts' in context

Implement Chain-of-Verification \(CoVe\) pattern: generate, verify with isolated queries, then revise before proceeding to next step.

Journey Context:
In multi-step reasoning \(ReAct, Plan-and-Execute\), the LLM generates an observation at step 2 \(e.g., 'the user wants X'\). By step 5, this assumption is treated as ground truth, but it was actually a hallucination. Standard CoT doesn't catch this because the model doesn't backtrack. The model becomes confidently wrong because each subsequent step reinforces the initial error \(autocatalytic drift\). Verification must happen \*between\* steps, not just at the end, using independent LLM calls or tool checks that don't share the biased context of the original reasoning chain.
