Publishes the base images deployed task containers will build on:
`triggerdotdev/node:{21,22,24,26}-bookworm` and
`triggerdotdev/bun:1.3-node20-bookworm`, each with a `-build` toolchain
variant, multi-arch, built from a pinned Debian snapshot so every
published layer is reproducible from recorded inputs and carries a
GitHub provenance attestation.
Publishing runs on manual dispatch and on merges touching
`base-images/`. Pull requests build without pushing.
