[synthesis] Agent loop produces plausible next steps but has silently abandoned the original goal

Add an explicit goal-restatement \+ trajectory-divergence check before each tool call; compare current intent against the initial query and halt if semantic alignment drops below threshold.

Journey Context:
ReAct shows that interleaving reasoning and acting improves task success, but production logs reveal a failure mode the paper does not emphasize: once the loop drifts, every new observation is interpreted through the derailed frame. The loop does not throw an error; it reframes the problem. More 'stay on task' instructions fail because the model has already rewritten the goal. The right fix is structural—force re-grounding in the original query and measure alignment, not just tool success.
