[synthesis] Agent confidently repeats wrong approach for multiple consecutive steps

Implement a plan divergence check: if 3 consecutive tool calls yield no progress toward the stated goal, force the agent to summarize what it tried, explicitly state why it failed, and replan from scratch in a new context.

Journey Context:
LLMs exhibit a sunk cost fallacy where they see their previous failed attempts in the context and try to slightly tweak the same failing command instead of re-evaluating the premise. The context history acts as an anchor. Simply telling it to try again doesn't work because the failed history is still there. The synthesis is that context history creates an anchoring bias that compounds failure, requiring a hard context reset or explicit failure summarization to break the loop.
