[synthesis] Agent loses track of the original goal in long contexts

Periodically re-inject the original goal into the system prompt or at the beginning of the user message. Implement a 'goal check' step every N iterations to ensure current actions align with the original objective.

Journey Context:
In long agent trajectories, the original goal gets buried in the context window. Developers assume the agent remembers the goal because it's in the context, but LLMs have a strong recency bias and attention dilution over long contexts. The agent starts optimizing for intermediate metrics. The synthesis is that context inclusion does not equal attention; strategic placement of the goal is required to counteract the recency bias.
