[synthesis] Agent loops without reasoning or makes impulsive tool calls leading to hallucinated actions

Enforce a strict Thought -> Action -> Observation loop in the system prompt. Require the model to output a reasoning block before any tool call. Do not allow tool calls without preceding reasoning.

Journey Context:
Models often try to guess the answer immediately or call tools without a plan. The ReAct paper showed that forcing a reasoning step significantly reduces hallucination and error rates. While newer models are better at implicit reasoning, explicit thought steps remain a robust architectural pattern for reliability.
