[synthesis] Agent drifts from original goal in long planning horizons due to recency bias

Periodically inject the original user objective and the high-level plan into the agent's context, and require a brief alignment check before starting a new major step.

Journey Context:
In long-running tasks, the agent's context fills with intermediate tool outputs and error recovery steps. The LLM's attention mechanism prioritizes recent tokens. The agent starts optimizing for local sub-problems \(e.g., fixing a linting error\) and completely forgets the original task \(e.g., 'add a new API endpoint'\). Re-injecting the primary goal combats context-window amnesia.
