   1、建议重构模型路由策略实现，支持用户自定义模型路由语义元句
          ~/.deepx/router/patterns/   追加4个级别的语义元句定义 deep.toml   complex.toml  medium.toml  simple.toml
   2、支持模型路由回降机制，进一步降低成本
   3、进一步细化模型路由策略

✨ feat: 引入语义模型优化本地模型路由策略
c3c0cfd 
- segmenter.yaml 独立配置文件(不污染 model.yaml)
- embedder: onnx 启动语义模型  默认使用bge-small-zh-v1.5  支持自动下载
- topic_tracking: true 启动主题追踪
- onnx_model: xxx  支持手动配置下载模型

add TopicGraph feature with ollama

fix: PR itmisx#219 issue 全部修复

1. modelPin 判断: m.modelPin == "" || m.modelPin == "auto" (原恒为 false)
2. activeModelID 兜底: else 分支加回退逻辑
3. CI: go vet self-assignment 删除 + TF-IDF 首篇文档向量全零修复
4. 话题切换冲突: 移除 TopicSwitch 提示(保留 TopicGraph 用于路由)
5. ONNX 路径: ortLibName build tag 分平台 + ORT 引擎路径改为 ~/.deepx/ocr/
6. ONNX mean pooling: 按 attention_mask 加权平均 + 归一化
7. 阈值分档: adjustedNewTopicThreshold() 按 embedder 类型返回不同值
8. token_type_ids: 补充缺失的 ONNX 模型输入(全零张量)
