fix(releases): strip prerelease and build metadata before version compare

Browse Source 
System.Version can't parse SemVer prerelease ("-alpha") or MinVer build
metadata ("+sha") suffixes, so an installed 1.0.2-alpha was treated as
unparseable. Reduce both sides to their numeric core before comparing.
