[synthesis] Agent takes confidently wrong consecutive steps due to plan rigidity and rationalization

Inject a 'state divergence check' after every failed tool call, forcing the agent to explicitly compare the current environment state against the expected state of its plan before proceeding.

Journey Context:
In ReAct-style agents, a failure in step 1 often doesn't cause replanning. Instead, the agent attempts step 2 of its original plan, rationalizing the failure as a minor hiccup. Because the agent is anchored to its initial plan, it ignores mounting evidence that the approach is fundamentally flawed. The 'Thought' step becomes a post-hoc rationalization rather than genuine reasoning. Forcing a divergence check breaks the anchor, compelling the agent to acknowledge the failure and re-evaluate the plan rather than blindly continuing.
