feat(transit): 添加参考文献解析功能并修复段落编号继承问题
新增了参考文献处理模块,支持按照 GB 7714 《文后参考文献著录规则》顺序编码制 解析和格式化参考文献。同时修复了段落替换过程中自动编号丢失的问题。 - 新增 transit/references.py 模块,提供参考文献解析和格式化功能 - 在 body.py 的 replace_placeholder 函数中实现段落编号属性的正确继承 - 修改 transit/__init__.py 导入新的参考文献处理函数 - 更新 transit/config.py 添加参考文献样式配置项 - 修改 transit/renderer.py 集成参考文献处理流程
