Adds internal/version with three vars (Version, Commit, BuildDate) set
via -ldflags -X at build time. When unset (e.g. plain `go build`
without LDFLAGS), runtime/debug.ReadBuildInfo() populates them from the
embedded vcs info so `go install`, `go run`, and ko-built images
(buildvcs is on by default) still produce something meaningful.
Wired through:
- Makefile: VERSION / COMMIT / BUILD_DATE resolved from `git describe`
/ `git rev-parse` / `date`. LDFLAGS plumbed into every go-build and
ko-build target (build-images, build-atectl, build-atenet,
build-demos).
- hack/install-ate.sh: untouched here — ko apply / resolve don't
accept --ldflags, and ko's buildvcs embedding gives Commit +
BuildDate automatically through runtime/debug.ReadBuildInfo() in
the version package's init() fallback.
All six binaries respond to `--version`:
- kubectl-ate and atenet (cobra): rootCmd.Version = version.String()
- ateapi, atelet, ateom-gvisor, podcertcontroller (flag): explicit
`-version` bool that prints and exits.
Sample output:
kubectl-ate version 3b0a0d5 commit=3b0a0d5c2... \
built=2026-05-26T14:16:53Z darwin/arm64
Closes the "kubectl-ate --version has nothing to print" gap; gives ops
a way to tell at a glance which commit a deployed substrate component
came from.
