[agent\_craft] Agent forgets initial instructions or early file contents after multiple tool calls

Implement a context sandwich pattern: re-inject the primary goal and critical constraints at the end of the context window \(or system prompt\) right before every LLM call, rather than relying on the original top-loaded prompt.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon. As tool outputs accumulate, the original system prompt and user goal get pushed to the top of the context and attention degrades. Agents often fail silently, hallucinating new goals. Simply increasing context size doesn't fix attention decay; it just delays it and increases cost. Re-injecting the goal at the bottom ensures it has the highest attention weight for the next generation step.
