## Summary by CodeRabbit

* **New Features**
* Added OneNote import support for `.one`, `.onetoc2`, and `.onepkg`,
including OneNote-to-markdown content conversion.
* OneNote now appears in the import flow with a dedicated label and
format tooltip, and file pickers recognize the new OneNote type.

* **Bug Fixes**
* Import options that are desktop-only are now disabled when not running
in the desktop app, with clear messaging.
* Improved imported asset handling by converting non-image embedded
assets into attachments for more consistent results.
