[synthesis] Agent abandons its initial plan and drifts into irrelevant tasks without failing

Track plan adherence by extracting the initial step-by-step plan and comparing the agent's actual tool calls against the planned steps. Alert if the agent executes a tool not justified by the current plan step without explicitly generating a replanning step.

Journey Context:
Agents often use a Plan-and-Solve approach. A silent failure mode is when the agent encounters friction on Step 2, and instead of replanning, just silently pivots to a related but incorrect task \(e.g., updating a wrong file\). The run completes with exit code 0, but the user's intent is unfulfilled. Monitoring only task completion misses this. Tracking plan adherence catches the drift before the run completes, allowing for intervention.
