Publish multi-arch (amd64 + arm64) container images#135
Merged
Conversation
The Dockerfile declared ARG TARGETOS/TARGETARCH but did not pin the builder stage to BUILDPLATFORM, so requesting linux/arm64 caused BuildKit to pull the arm64 golang image and run the entire build under QEMU emulation. This pins the builder to the runner's native architecture and cross-compiles via GOARCH, which is the standard fast path for pure-Go projects. Also threads version/gitCommit/gitTreeState/buildDate through -ldflags -X so images carry build metadata, and bumps the shared publish-docker workflow to v1.13.1 to enable the platforms input (linux/amd64,linux/arm64). Unblocks Apple Silicon developers who currently cannot pull the published image without emulation. Local multi-arch buildx build completes in ~49s on an M-series laptop.
