Description

issue description

What happened?
When attempting to convert a Microsoft Word (.doc) file to Markdown, markitdown fails with an UnsupportedFormatException indicating that no converter recognized the stream’s format:

`INFO - File download completed in 0.85s. Content-Type: application/msword, Content-Length: 102912

markitdown._exceptions.UnsupportedFormatException: Could not convert stream to Markdown. No converter attempted a conversion, suggesting that the filetype is simply not supported.

ValueError: Failed to convert file: Could not convert stream to Markdown. No converter attempted a conversion, suggesting that the filetype is simply not supported.`

Research direction

Start by reproducing conversion of a Microsoft Word .doc stream with Content-Type application/msword, then inspect how format detection and converter selection handle the stream. Done means the reported .doc input converts to Markdown instead of raising UnsupportedFormatException.
