Multiple customers have now requested scripts for setting hostnames on macOS, and a couple for Linux. This adds scripts to the solutions folder for that purpose. Linux tested against `Ubuntu 26.04` and `openSUSE Tumbleweed` macOS tested against `Tahoe 26.4.1` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **Documentation** * Added an automated Linux hostname configuration solution that derives a hostname from the device serial, applies it system-wide, and updates host entries. * Added an automated macOS hostname configuration solution that sets ComputerName/LocalHostName/HostName from the device serial and reports the new hostname. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
