[cost\_intel] o1 causing 30s\+ latency per step in multi-step agent workflow

Use 4o for tool-calling agents with <5s step latency; use o1 only for the 'planning' phase in offline strategy generation, not real-time execution

Journey Context:
Agentic workflows require tight tool-use loops \(LLM → tool → LLM\). o1's 10-60s latency per step makes it unusable for interactive agents \(coding assistants, research agents, robotic control\). The cost compounds exponentially with step count \(n steps × $15 vs n steps × $0.50\). The architectural fix is hierarchical: o1 generates the strategy/plan once \(offline or initial step\), 4o executes the tool calls in the loop. Signature of wrong architecture: agent taking >30s between tool calls.
