The go directive in go.mod should only specify the major and minor version (e.g., go 1.25), not the patch version. Including the patch version 1.25.5 is non-standard. The patch version of Go used for building is specified elsewhere (in the build environment), and the go.mod directive should only reflect the minimum required major.minor version for module semantics.
