--version printed "dev" for any binary not built with make build, so a user running a go install build could not say what version they had. resolveVersion now falls back to the module version from runtime/debug.ReadBuildInfo() when the build-time stamp is absent, ignoring the "(devel)" of a local build. The stamped value still wins when present. It takes the build info as an argument, so a test covers the choice without a real build. Model: opus-4-8
