[cost\_intel] Using o1 for every step in a multi-step agent workflow

Use Haiku/4o-mini for tool execution and data gathering, then o1-mini for final synthesis/critique; reduces cost by 80% while preserving 95% of reasoning quality.

Journey Context:
Most agent steps are deterministic retrieval/tool calls requiring no planning; reasoning is only needed at decision points or final verification. The 'fast agent \+ slow critic' pattern amortizes reasoning cost across many cheap actions.
