fix: 修复记忆系统自循环与计算层污染

- 删 syncGraphToDocs(): Graph 快照不再写入 Document，避免污染向量索引和三层隔离
- 删 toolCallRing(): 已被工具 NoMemory/Cleaner 机制取代，不再需要独立环形缓冲
- 加 toolOutputClean 回调线程 Prune→ContextToDoc: 归档时按 NoMemory 跳过、Cleaner 清洗后再过 jieba，原文保留
- 加 eval_status 持久化 (RecallPending/UpdateEvalStatus/ResolveEvaluating): 避免重复 LLM 评估
