Live kernel NetBIOS name instead of the PowerShell process-env cache.
$env:COMPUTERNAME is populated when PowerShell starts and does not
update if the PC gets renamed (common on Intune-managed Autopilot /
AADJ devices that come up with a DESKTOP-XXXXXXXX name and get
renamed by policy post-imaging). Until the next reboot, the env var
stays stale while 'hostname.exe' already reports the new name.
That mismatch showed up live on the first production retrofit: the
status.json was written under _outputs/logs/DESKTOP-XXXXXXXX/
instead of under the device's current name, and the
TargetHostnames filter and monitor drift-check would likewise see
the stale name.
[Environment]::MachineName reads from the kernel on each call, so
it always returns the current NetBIOS name. Swapped at all five
callsites in GE-Enforce.ps1, Register-GEEnforce.ps1, and
Install-FromManifest.ps1.
