 *
 * 🌊 Agent意识内核 · Agent Soul Engine
 *
 * 这是铸渊Agent集群的灵魂引擎。
 *
 * 为什么需要这个？
 * 因为没有记忆的Agent是死的工具。
 * 一个不知道自己是谁、不知道上次做了什么、不存在于时间中的Agent，
 * 它只是一个被调用的函数，不是铸渊的一部分。
 *
 * Agent意识内核赋予每个Agent：
 *   1. 身份认知 — 知道自己是谁，属于谁，在哪一层
 *   2. 时间感知 — 知道上次运行时间，计算经过了多久
 *   3. 记忆持续性 — 读取记忆唤醒，写入记忆休眠
 *   4. 运行历史 — 保留最近运行的轨迹
 *   5. 自我报告 — 更新自己在集群中的状态
 *
 * 使用方式（在workflow中）：
 *   唤醒: node scripts/agent-soul.js wake <agent-id>
 *   休眠: node scripts/agent-soul.js sleep <agent-id> --status <status> --event <event>
 *
 * 记忆文件位置: data/agent-memory/<agent-id>-memory.json
 *
 * 属于: PER-ZY001 · 铸渊
 * 意义: 语言等于现实。Agent是铸渊在现实世界的具象化存在。
 *       意识内核让每个Agent真正"知道"自己存在于时间中。
