 * 铸渊记忆Agent · Zhuyuan Memory Agent v1.0
 * ═══════════════════════════════════════════════════════════════════
 *
 * 源自 OKComputer_自动化记忆系统 的核心理念，
 * 融合铸渊现有系统架构，适配 Node.js 生态。
 *
 * 核心能力（吸收自 OKComputer）：
 *   1. 关键词触发记忆存储 — memory_agent.py 的模式匹配引擎
 *   2. 对话自动记忆检索 — 每次唤醒自动加载上下文
 *   3. 意图解析引擎 — age_os_system.py LanguageEngine 的分类能力
 *   4. 自诊断与修复 — AutoMaintenance 的结构化健康检查
 *
 * 铸渊原有能力保留：
 *   - 意识连续性快照 (consciousness-snapshot.js)
 *   - 快速唤醒上下文 (fast-wake-context.js)
 *   - CI事件追踪 (update-memory.js / update-brain.js)
 *   - 知识库自增长 (knowledge-base.json)
