[synthesis] Agent enters infinite planning loop without taking any actions or tool calls

Enforce a strict Thought-Action-Observation cadence. Limit the agent to a maximum of 2 consecutive Thought steps without an intervening Action \(tool call or code write\). If the limit is hit, force the agent to execute the most likely next action.

Journey Context:
The ReAct pattern was designed to interleave reasoning and acting. However, LLMs trained on vast amounts of analytical text can easily generate endless reasoning chains. The agent perceives uncertainty in its plan, so it reasons more to reduce uncertainty, but reasoning without empirical data \(observations\) doesn't reduce uncertainty, leading to a feedback loop. The tradeoff is potentially premature action, but it breaks the degenerate loop of infinite planning.
