[agent\_craft] Agent forgets initial system prompt or early tool outputs after long context accumulation

Place critical instructions at the very beginning and very end of the context window. Periodically re-inject critical constraints during long agentic loops.

Journey Context:
LLMs suffer from the 'lost in the middle' phenomenon where attention degrades for information in the middle of long contexts. As tool outputs accumulate, early system constraints get overshadowed. Simply appending to context degrades instruction following. Re-injection or sandwiching ensures the model attends to its core directives.
