[frontier] Hardcoded human approval steps block agent execution

Model 'Ask Human' as an asynchronous tool the agent can call when uncertain, allowing the orchestration layer to suspend the thread until the human responds, rather than interrupting the flow.

Journey Context:
If you hardcode approval steps, the agent cannot adapt to unexpected situations where it needs more info, nor can it skip approval for low-risk steps. By making it a tool, the LLM decides when it lacks confidence. The infrastructure handles the async wait, allowing the agent to gracefully pause and resume state without blocking the entire system.
