ghcr.io/opentofu/opentofu:1.11 has an ONBUILD that prints a deprecation warning and runs `exit 1` — the maintainers explicitly disabled using that image as a base in 1.10+ (opentofu/opentofu#1931). Build pipeline 810 hit it with `error building stage: ... exit status 1`. Switch the base to alpine:3.21 and install the tofu binary directly from the GitHub release zip (TOFU_VERSION=1.11.0 ARG, matches what the pipeline previously pinned).
