## Summary by CodeRabbit

* **New Features**
* On iOS devices, the app and editor version numbers in the About
section now display only the main version (e.g., "0.23.0"), hiding any
additional suffixes.
* **Other**
* No visible changes for users on non-iOS platforms; full version
strings remain displayed.
