Description
Microsoft markitdown (v0.0.2) 目前对旧版二进制 OLE2 复合文档的格式识别不够精准。当遇到 .doc 文件时，它错误地将其判定为 Excel .xls 文件并强行调用 pandas + xlrd 去读取工作簿，导致 100% 触发 XLRDError 异常抛错！

Research direction
Reproduce the failure with an old binary .doc file using MarkItDown v0.0.2, then trace the format-detection path that routes it to pandas and xlrd. Confirm the fix by ensuring .doc input is no longer treated as an Excel workbook and does not raise XLRDError.
