ln-822-nuget-upgrader

SUSPICIOUS: the core behavior matches a NuGet upgrade skill, but its footprint is broader than a purely local upgrader because it installs an unpinned third-party tool and may pull remote instruction files and web-sourced migration guidance at runtime. No clear credential harvesting or exfiltration is present, so this is not malware, but the install-trust and indirect-content risks make it medium risk overall.
