required to bump DMR in DD to latest version

Hey - I've found 1 issue, and left some high level feedback:

• Go version is hard-coded in multiple places (three workflows, Dockerfiles, Makefile, go.mod); consider centralizing it via a reusable workflow input or a shared build arg/variable to avoid divergence on the next version change.
• The Dockerfile and CLI Dockerfile use ARG GO_VERSION=1.25 while the Makefile/go.mod use 1.25.8; if the intent is to pin to a specific patch version everywhere, consider aligning these to avoid subtle differences between local builds and container builds.

**issue (bug_risk):** The `go` directive should use only major.minor (e.g., `go 1.25`) rather than a full patch version.

Using a patch version in `go.mod` will cause `go` tooling errors (e.g., `invalid go version`). Please change this to `go 1.25` and keep the specific patch level (1.25.8) enforced via CI/Docker or other tooling instead.

Code Review

This pull request aims to downgrade the Go version. However, both the original version (1.26.0) and the new version (1.25.8) are not existing Go releases. This is a critical issue that will cause build failures for anyone using standard Go toolchains or Docker, as the specified Go versions and corresponding Docker images do not exist. I've added comments to all affected files pointing out this issue. Please correct the Go version to a valid, released version across all files.

LGTM!

Go version from go.mod: 1.25.8

All files are in sync.

Was the problem that go.mod required go1.26? If that's the case, then a good option is also to keep the version in go.mod at an older version (generally "latest" and "latest-1" are supported by upstream Go), and for CI you can specify the version separately; also look at;

Thanks! Yes, we downgraded so we can import it in projects that still use 1.25. I'm totally fine with using 1.25, too.
