[agent\_craft] Context rot from stale tool outputs filling the window

Implement a tiered memory system where tool outputs are aggressively evicted or summarized after use, while pinning the core task definition and system instructions.

Journey Context:
Agents often keep the full JSON response of a \`cat file\` or \`grep\` call in context forever. As the task progresses, this early context becomes irrelevant but consumes tokens, pushing out newer, more relevant context. Naive truncation loses the task; summarization loses details. The right call is to externalize large outputs to an archival memory \(vector store or file\), and only keep the summary or extract in the immediate context, implementing a strict token-limit eviction policy \(LRU on tool outputs, but pin system/task\).
