[agent\_craft] Long-running agent loses track of the original goal due to recursive summarization of prior steps

Maintain an immutable epistemic core \(the original goal and hard constraints\) in a separate memory block that is never summarized, and inject it into every LLM call alongside the rolling summary of recent actions.

Journey Context:
As agents run for many steps, they compact history. Each compaction loses a bit of fidelity. Over 50 steps, the original goal gets mutated into something else entirely \(summarization drift\). By separating the context into Immutable Core and Mutable History, the agent always has the pristine original intent. The mutable history can be aggressively summarized without risking goal drift.
