Function CombinePackageData

agent-source-code/internal/packages/packages.go:161–194

CombinePackageData combines and deduplicates installed and upgradable package lists. installedPackages must contain full package info (including Description from dpkg-query). Descriptions and SourceRepository are preserved from installed packages for both upgradable and non-upgradable.
