Replaces the OCI-push flow with a bundle-based one that mirrors the
kernel catalog (publish-kernel.sh / kernelcat).
- scripts/make-golden-bundle.sh: docker build → docker create → docker
export | banger internal make-bundle → .tar.zst. Defaults target
debian-bookworm / generic-6.12 / x86_64; pinned --size 4G to leave
headroom for first-boot installs and in-VM apt use.
- scripts/publish-golden-image.sh: rewritten to call make-golden-bundle,
rclone upload to R2 (banger-images bucket, images.thaloco.com), and
jq-patch internal/imagecat/catalog.json with URL / sha256 / size.
--skip-upload stops after bundle build and copies to dist/.
make-bundle default ext4 sizing also bumped from +25% to +50% headroom
(mkfs.ext4 needs room for inode tables, block-group metadata, journal,
and the default 5% reserved-blocks margin). The old 25% was too tight
for the ~950 MB golden rootfs and aborted with "Could not allocate
block".
End-to-end smoke (local): golden Dockerfile → 286 MB tar.zst bundle
with correct manifest, valid ext4, and all banger units + vsock agent
present.

Debian bookworm with two clearly-labeled sections:
- ESSENTIAL: systemd, openssh-server, ca-certificates, curl, iproute2.
- OPINION: git, jq, ripgrep, fd, build-essential, shellcheck, mise,
Docker CE (+ Compose v2 + buildx), tmux, htop, and friends.
Per-VM identity stripped at build time: /etc/machine-id cleared,
SSH host keys removed with a ssh.service drop-in that runs
`ssh-keygen -A` on first start so each VM gets a unique set.
The script is a parameterized wrapper around `docker build`; it also
supports `--push` to an OCI registry, which will be removed once the
bundle pipeline is in place.
