The builder stage is pinned to Go 1.25, but the final image installs golang-go from Debian without pinning a matching Go toolchain version. Since gopls shells out to the go toolchain for analysis/build operations, a mismatch here can cause unexpected behavior when analyzing modules with go 1.25.0 (see go.mod). Consider ensuring the final image provides the same Go version (e.g., copy /usr/local/go from a Go 1.25 stage or install a version-pinned Go toolchain), rather than relying on the distro package version.
