• Errors and warnings now go to stderr instead of stdout, so they no longer pollute pipelines.
• Fixed grepip --include-cidrs / --include-ranges dropping every CIDR and range match when combined with --exclude-reserved (-x).
• Fixed winget install ipinfo leaving an unusable binary: the Windows release zip now contains ipinfo.exe instead of the versioned filename.
• Install scripts (deb.sh, windows.ps1) now fail loudly when installation does not succeed, instead of printing a success message anyway.
