## Summary by CodeRabbit
* **New Features**
* iOS/iPadOS devices managed via MDM now include reported supplemental
OS version text (e.g., Rapid Security Response suffixes) in the
displayed OS version string.
* **Bug Fixes**
* Supplemental extras are validated; invalid values are ignored.
Combined version strings are length-limited and safely truncated.
* **Tests**
* Added tests for supplemental handling, validation, fallback, and
truncation.
