## 💡 开箱即用示例
### 添加记忆
```typescript
// 添加长期记忆
await skills.smartMemoryManager({
  action: "add",
  content: "用户喜欢喝咖啡，不加糖，每周三下午喝奶茶",
  type: "long-term",
  persist: true
});
```

### 搜索记忆
```typescript
const result = await skills.smartMemoryManager({
  action: "search",
  query: "用户喜好",
  limit: 3,
  searchMode: "hybrid" // 关键词+语义混合检索
});
```

### 生成会话摘要
```typescript
const summary = await skills.smartMemoryManager({
  action: "summarize",
  typeFilter: "short-term",
  maxTokens: 500
});
```

### 持久化与加载
```typescript
// 保存所有记忆到磁盘
await skills.smartMemoryManager({
  action: "save",
  persistPath: "./my-memory.json"
});

// 从磁盘加载记忆
await skills.smartMemoryManager({
  action: "load",
  persistPath: "./my-memory.json"
});
```

## 🔧 技术实现说明
