easterbrooka teaches Mike to read Outlook .msg files

Most lawyers don't send each other clean RFC-822 email files. They forward Outlook items, which save as a proprietary binary format that ordinary parsers can't touch. easterbrooka closed that gap by writing a small adapter that takes the output of a third-party Outlook reader and reshapes it to look exactly like a regular parsed email inside Mike.

The payoff is that nothing downstream had to change. The email viewer, the document-reading tool the chat uses, and the structure outline all treat Outlook messages and standard emails identically - sender, recipients split into to/cc, date, attachment list. Six new tests cover the messy edges: missing headers, unparseable dates, attachments with no filename. Uploads and drag-drop were widened to accept the new file extension.
