After running notebooklm source list --json -n [notebook_id], i can see a source object with SourceType.MARKDOWN that is the report I'm trying to download. However when I run notebooklm source fulltext [source_id] -n [notebook_id] it's giving me the content stripped of markdown formatting.

Maybe can create a flag --markdown that will allow preserving the markdown formatting of the report?

From reading #193, I understand that there's a need for plaintext format, but it breaks tables in the report with each cell in a new line.
