[synthesis] Agent enters an infinite loop of replanning without executing after encountering an unexpected state

Enforce a 'plan-then-execute' lock: once a plan is generated, the agent must execute at least one tool call before it is allowed to re-evaluate the plan. Limit consecutive 'thought' steps without tool use to 1.

Journey Context:
When an agent encounters a state that doesn't perfectly match its expected plan, it often defaults to replanning. If the environment is dynamic or the agent's mental model is slightly off, it will replan, find another discrepancy, and replan again. This 'analysis paralysis' loop derails silently because the agent is technically doing useful reasoning, but making zero progress. By forcing tool execution \(even if imperfect\), the agent alters the environment state, providing new ground-truth information that breaks the static replanning loop.
