[agent\_craft] Agent enters infinite observation-thought-action loops without converging on final answer

Implement a strict 'Answer' action type that emits a final tag and terminates the loop; enforce a maximum reasoning step limit \(e.g., 5-10 iterations\) and require the agent to summarize and exit if the limit is reached rather than continuing.

Journey Context:
ReAct patterns \(Reasoning \+ Acting\) often lead to 'analysis paralysis' where the agent keeps gathering observations without synthesizing them. The root cause is missing terminal states in the action space. The fix requires explicit 'termination actions' in the prompt: 'If you have sufficient information, you MUST use the Answer action with final output.' Hard iteration limits prevent runaway token consumption. This differs from standard ReAct which assumes implicit termination.
