lanyuanxiaoyao 1aea561277 refactor: 重构 Reader 内部工具函数到独立模块
- 新增 scripts/readers/_utils.py 作为 Reader 内部共享工具模块
- 将 parse_with_markitdown 等函数从 core/markdown.py 迁移到 _utils.py
- 函数重命名:parse_with_xxx → parse_via_xxx,_unstructured_elements_to_markdown → convert_unstructured_to_markdown
- 更新 17 个 Reader 实现文件的 import 路径
- 从 core/__init__.py 移除已迁移函数的导出
- 新增测试文件 tests/test_readers/test_utils.py
- 新增 spec 文档 openspec/specs/reader-internal-utils/spec.md

这次重构明确了模块边界:core/ 提供公共 API,readers/_utils.py 提供 Reader 内部工具
