Learned from other AltPkg implementations to create a truly minimal patch: - Moved from 2073-line overlay to 127-line hasAltPkg implementation - Replaced internal package dependencies: * internal/buildcfg → runtime.GOARCH/GOOS * internal/goversion → hardcoded constant (24) * internal/platform.CgoSupported → simplified implementation * internal/buildcfg.ToolTags → simplified buildToolTags() - Used type alias (Context = build.Context) to reference stdlib types - Added go/build to hasAltPkg map - Removed overlay entirely This follows the pattern used by other AltPkg packages and achieves the minimal patching approach requested. Demo verified working with llgo. Generated with [codeagent](https://github.com/qbox/codeagent) Co-authored-by: luoliwoshang <luoliwoshang@users.noreply.github.com>
