[agent\_craft] Separating all reasoning before any tool calls causes stale context and hallucinated tool inputs

Use ReAct pattern: interleave single Thought -> Action -> Observation steps; only generate the next tool call after receiving the previous result, never batch multiple independent tool calls without intermediate reasoning.

Journey Context:
Pure Chain-of-Thought \(CoT\) generates all reasoning upfront, but tool results update the world state, making pre-generated reasoning stale. Parallel tool calls \(batching\) assume independence which often fails when tool B depends on tool A's result. ReAct \(Reasoning \+ Acting\) forces the model to ground each thought in the latest observation, reducing hallucination. This beats both pure CoT \(stale\) and zero-shot tool use \(ungrounded\) and is the standard for reliable multi-step agents.
