[frontier] Agent gets stuck in tool loops or uses tools for reasoning that should be internal

Explicitly separate Reasoning \(internal monologue\) from Acting \(tool use\). Force the agent to output a 'Thought' before any 'Action', and validate that tools are only called when external data is strictly required.

Journey Context:
The 'tool hammer' anti-pattern: agents call search or calculator for arithmetic the LLM can do, or worse, they 'think' by writing to files. This creates latency and failure surface. ReAct \(Reasoning \+ Acting\) formalizes the loop: Thought -> Action -> Observation. The key insight is that the LLM needs a 'scratchpad' \(the Thought\) that is NOT sent to the tool. Production agents fail when they stream everything to the user or tool without this intermediate reasoning layer. Alternatives like 'Direct Tool Calling' work for simple demos but scale poorly.
