[synthesis] Agent loses track of original goal in long execution traces

Periodically re-inject the original goal and high-level plan at fixed intervals \(e.g., every 5 steps\) into the moving window of the context, rather than relying on the initial system prompt alone.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon. In a 20-step agent trace, the original goal is thousands of tokens away from the current step. The agent begins to drift, optimizing for local coherence \(making the next step fit the last step\) rather than global coherence \(achieving the original goal\). Simply putting the goal in the system prompt isn't enough if the context window is large. Re-injecting the goal periodically ensures it remains in the high-attention zone of the context window.
