[agent\_craft] ReAct reasoning traces consume tokens without improving tool selection

Interleave thought and action only when the observation changes the plan; otherwise batch tool calls

Journey Context:
The ReAct pattern \(Reasoning \+ Acting\) suggests generating a 'Thought' before every tool call to explain the reasoning. However, for deterministic tool chains \(e.g., read\_file → grep → read\_file\), generating verbose reasoning traces between every step wastes tokens and increases latency without improving accuracy. The optimization is to generate a reasoning trace only when an observation changes the high-level plan \(e.g., 'The file doesn't exist, so I need to create it instead'\). Otherwise, batch multiple tool calls in a single assistant message without intermediate reasoning tokens.
