[synthesis] Retry loops that compound errors by treating symptoms as root causes

Implement root-cause verification: before retrying, require explicit hypothesis of failure mechanism and validate against previous attempts to prevent symptom-fix cascades

Journey Context:
ReAct papers discuss reflection, and LangGraph implements retries, but the synthesis reveals the 'symptom-fix cascade': when agents retry, they often fix surface symptoms \(e.g., 'file not found' → create file\) without verifying if this addresses the root cause \(e.g., wrong path variable\). This creates a drift where each 'fix' moves further from the original intent. The synthesis shows that retry logic must validate the causal hypothesis against the failure history, not just the immediate error message.
