Brings back linux/amd64 container images using a matrix build strategy with native runners for each architecture (no QEMU cross-compilation): - arm64: built on ubuntu-24.04-arm (existing) - amd64: built on ubuntu-24.04 (new) Both architectures build in parallel, then a manifest job merges them into multi-arch tags on ECR and GHCR. This keeps the per-arch build fast (~5min native vs ~20min QEMU) while restoring amd64 support. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
docker manifest push prints the manifest digest to stdout. Capture it and pass it through to the Charts deployment trigger so the deployed image is pinned to the exact multi-arch manifest that was built. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

The duckgres container image now ships as a multi-arch manifest (arm64 + amd64) via PostHog/duckgres#386, so the platform pin is no longer needed and was preventing the image from running on amd64 dev machines. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Summary

Why
AMD64 support is needed for local development and non-Graviton environments. The original removal (#348) was to avoid slow QEMU cross-compilation (~20min). Native runners solve this — each arch builds in ~5min natively, in parallel.
