Identifies high-risk interpreters and LOLBins spawned by ConfigurationRemotingServer.exe, the WinGet Configuration
remoting worker. Legitimate WinGet configuration may invoke some of these rarely; unexpected children can indicate abuse
of the WinGet Configuration COM API to run attacker-controlled actions through Microsoft-signed plumbing, as described
in public research on DSCourier.
