[synthesis] Agent creates a perfect plan but immediately deviates from it on the first action

Use a 'plan-then-execute' architecture where the plan is saved as a structured artifact, and the execution step must explicitly reference and update the current step in the plan before choosing a tool.

Journey Context:
Synthesizing Plan-and-Solve prompting with ReAct's action-observation loops reveals that generating a plan and an action in the same continuous stream causes the action to ignore the plan due to recency bias. In standard loops, the agent thinks, acts, and observes. When the agent 'thinks,' it writes a brilliant multi-step plan, but the very next token generates an action that reacts to the immediate context. By forcing the plan into a separate, referenced state, the execution phase is grounded.
