v1.0.0 — First stable release

CentOS Stream 10 bootc base images with ZFS and NVIDIA kernel modules,
built and signed through the dunn.dev/immutable/pipeline CI/CD components.

This tag marks the first release where the full build chain runs cleanly:
upstream mirror, DKMS module builds, three image variants (base, zfs,
zfs-nvidia), cosign signatures, SBOMs, and automated :stable promotion.

Image variants:
  - basec/base         — minimal CentOS Stream 10 bootc
  - basec/zfs          — base + ZFS kernel modules
  - basec/zfs-nvidia   — base + ZFS + NVIDIA open kernel modules

Versions at time of release:
  - Kernel: 6.12
  - ZFS: 2.2.9
  - NVIDIA: 595.45
