重构: String→newtype 强类型 + 工程清理

- df-types: ExecutionId/ToolCallType 从 type 别名改为 newtype 结构体
- df-ai-core: 新增 ToolType newtype / MessageStatus 枚举,
  ChatMessage.status 从 Option<String> 改为 Option<MessageStatus>
- provider: is_active() 改用 MessageStatus::Active 模式匹配
- context/chat/conversation: 构造站点更新为枚举变体
- .gitignore: 添加分析脚本排除项,清理根目录临时文件
- Batch.md: 更新最新提交与新增 Batch 37 记录
