mineru-2.7.0-released

## What's Changed

- 2025/12/30 2.7.0 Release
  - Simplified installation process. No need to separately install `vlm` acceleration engine dependencies. Using `uv pip install mineru[all]` during installation will install all optional backend dependencies.
  - Added new `hybrid` backend, which combines the advantages of `pipeline` and `vlm` backends. Built on vlm, it integrates some capabilities of pipeline, adding extra extensibility on top of high accuracy:
    - Directly extracts text from text PDFs, natively supports multi-language recognition in text PDF scenarios, and greatly reduces parsing hallucinations;
    - Supports text recognition in 109 languages for scanned PDF scenarios by specifying OCR language;
    - Independent inline formula recognition switch, which can be disabled separately when inline formula recognition is not needed, improving the visual effect of parsing results.
  - Simplified engine selection logic for `vlm/hybrid` backends. Users only need to specify the backend as `*-auto-engine`, and the system will automatically select the appropriate engine for inference acceleration based on the current environment, improving usability.
  - Switched default parsing backend from `pipeline` to `hybrid-auto-engine`, improving out-of-the-box result consistency for new users and avoiding cognitive differences in parsing results.
  - Added i18n support to gradio application, supporting switching between Chinese and English languages.
 
- 2025/12/30 2.7.0 发布
  - 简化安装流程，现在不再需要单独安装`vlm`加速引擎依赖包，安装时使用`uv pip install mineru[all]`即可安装所有可选后端的依赖包。
  - 增加全新后端`hybrid`，该后端结合了`pipeline`和`vlm`后端的优势，在vlm的基础上，融入了pipeline的部分能力，在高精度的基础上增加了额外的扩展性：
    - 从文本pdf中直接抽取文本，在文本pdf场景原生支持多语言识别，并极大减少解析幻觉；
    - 通过指定ocr语言，在扫描pdf场景下支持109种语言的文本识别；
    - 独立的行内公式识别开关，在不需要行内公式识别的场景下可单独关闭，提升解析结果视觉效果。
  - 简化`vlm/hybrid`后端的引擎选择逻辑，用户只需指定后端为`*-auto-engine`，系统会根据当前环境自动选择合适的引擎进行推理加速，提升易用性.
  - 默认解析后端从`pipeline`切换至`hybrid-auto-engine`，提升新用户开箱即用的结果一致性，避免出现解析结果认知差异。
  - gradio应用增加i18n适配，支持中英文两种语言切换。
