feat: Add persistent browsing history

- Implement HistoryManager for JSON persistence (~/.config/tut/history.json)
- Auto-record page visits with URL, title, and timestamp
- Update visit time when revisiting URLs (move to front)
- Limit to 1000 entries maximum
- Add :history command to view browsing history
- History entries are clickable links
- Add test_history test suite

# TUT 2.0 - 下次继续从这里开始
## 当前位置
- **阶段**: 代码整合完成,准备发布 v2.0.0
- **进度**: 所有核心功能已完成,代码库已整合简化
- **最后提交**: `refactor: Consolidate v2 architecture into main codebase`
- **阶段**: Phase 7 - 历史记录持久化 (已完成!)
- **进度**: 历史记录自动保存,支持 :history 命令查看
- **最后提交**: `feat: Add persistent browsing history`

书签存储在 `~/.config/tut/bookmarks.json`
### 2. 查看历史记录
- **:history** 或 **:hist** - 查看浏览历史
历史记录存储在 `~/.config/tut/history.json`
## 已完成的功能清单
### Phase 7 - 历史记录持久化
- [x] HistoryEntry 数据结构 (URL, 标题, 访问时间)
- [x] JSON 持久化存储 (~/.config/tut/history.json)
- [x] 自动记录访问历史
- [x] 重复访问更新时间
- [x] 最大 1000 条记录限制
- [x] :history 命令查看历史页面
- [x] 历史链接可点击跳转
### Phase 6 - 异步HTTP
- [x] libcurl multi接口实现非阻塞请求
- [x] AsyncState状态管理 (IDLE/LOADING/COMPLETE/FAILED/CANCELLED)
