- make_dist_bundle.sh: assemble dist/coderai-docker-dist.tar containing the image
  tarball (docker save | pigz), the coderai-docker runner (run_oci.sh, image tag
  pinned), install.sh and README. Stages under dist/ (not tiny /tmp) and hardlinks
  the multi-GB image tarball instead of copying it.
- dist-bundle/install.sh: docker-load the image (sudo-fallback for daemon access)
  then install the coderai-docker runner to /usr/local/bin (root) or
  ~/.local/usr/bin (user, added to ~/.bashrc PATH if missing).
- build_oci_image.sh: after a successful build, export + bundle for distribution
  by default (--no-dist to skip).
- run_oci.sh: default image tag -> coderai:dist (matches what's shipped/loaded).
