Subject: [PATCH] simplify CI to docker build, pin all image refs by SHA

- Replace convoluted CI workflow (setup-go, install golangci-lint, install
  goimports, make check) with simple 'docker build .' per repo policy
- Pin Docker base images by SHA256 hash instead of mutable tags
- Pin golangci-lint and goimports by commit hash instead of @latest
- Add binutils-gold for linker compatibility on alpine
- Run on all pushes, not just main/PR branches
