IronClaw ships only linux/amd64 Docker images today, blocking native runs on Apple Silicon, Graviton, and Raspberry Pi 4/5 (arm64). The Cranelift backend already supports aarch64, so the gap is purely in the build matrix. This adds linux/arm64 to both image builds: - .github/workflows/docker.yml (regular + worker) - .github/workflows/rebuild-release-image.yml (runtime + final) Plus a docker/setup-qemu-action step before each Buildx setup so the amd64 GitHub runner can emit the arm64 image via emulation. The inline comment notes the ~2-3x build-time hit and suggests swapping to a native arm64 runner if/when one is available. Dockerfile header comment: removed the `--platform linux/amd64` example (host-arch is the right default once the official images go multi-arch) and added a multi-arch buildx example. Confirmed feasible by @gcaguilar's PoC fork; only armv7 (32-bit) is blocked, tracked separately in #1339. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Code Review
This pull request updates the build instructions in the Dockerfile to include commands for both host-architecture and multi-architecture builds using Docker Buildx. There are no review comments to address, and I have no feedback to provide.

Maybe it would be better to do a native build instead of using QEMU, |

Summary
Closes #3168.
IronClaw ships only `linux/amd64` Docker images today, blocking native runs on Apple Silicon, AWS Graviton, Raspberry Pi 4/5, and the broader arm64 fleet. Cranelift (the WASM JIT) already supports `aarch64`, so the gap is purely in the publish matrix.
What this changes
.github/workflows/docker.yml— adds `docker/setup-qemu-action` (pinned by SHA) and switches both image builds (`ironclaw` + `ironclaw-worker`) to `platforms: linux/amd64,linux/arm64`..github/workflows/rebuild-release-image.yml— same treatment for both build paths (`runtime` target + final-stage fallback).Dockerfileheader — removed the `--platform linux/amd64` example (host-arch is the right default for a developer once the official images go multi-arch) and added a Buildx multi-arch example.Cost / risk
QEMU emulation on the amd64 runner adds roughly 2-3x to the arm64 build time vs amd64. If that bites CI minutes, the right next step is provisioning a native arm64 runner (the inline comment in both workflows points at this). Until then, emulation is the correct tradeoff for parity.
Confirmation
@gcaguilar's PoC fork run already showed this works end-to-end: https://github.com/gcaguilar/ironclaw/actions/runs/25252983548. Only armv7 (32-bit) is blocked, which is tracked separately in #1339.
