[agent\_craft] Agent forgets initial goal or system instructions after long tool-use sequences

Hoist the primary directive and critical constraints to the very bottom of the context window \(closest to the generation point\) right before the LLM call, rather than leaving them buried at the top.

Journey Context:
LLMs suffer from the 'Lost in the Middle' phenomenon: they attend strongly to the beginning and end of a context, but forget the middle. As tool outputs accumulate, the original system prompt gets pushed into the middle and diluted. Re-injecting the core goal at the end ensures it dominates the attention mechanism during generation.
