v0.9.55, build 230 (2025-12-xx xx:xx UTC)

Added support for newer Mistral models (Mistral 3, Voxtral, and Magistral).
Added a description field to local data sources (preview feature) so that the data selection agent has more information about which data each local source contains when selecting data sources.
Improved the document analysis assistant (in preview) by adding descriptions to the different sections.
Improved the document preview dialog for the document analysis assistant (in preview), providing Markdown and plain text views for attached files.
Improved the ID handling for configuration plugins.
Fixed a bug in the local data sources info dialog (preview feature) for data directories that could cause the app to crash. The error was caused by a background thread producing data while the frontend attempted to display it.
