feat(ci): improve multi-platform image build - #5
Merged
Conversation
Split the Docker publish workflow into per-platform build jobs (amd64 on ubuntu-latest, arm64 on a native arm runner) that push by digest, plus a merge job that assembles the multi-arch manifest. Tagging is now handled by docker/metadata-action, all actions are pinned to commit SHAs, and per-platform GHA build caches are used. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What this PR changes
Reworks the Docker publish workflow for proper multi-platform image builds:
linux/amd64builds onubuntu-latestandlinux/arm64builds natively onubuntu-24.04-arm, eliminating slow QEMU emulation for the arm64 build.mergejob assembles and pushes the multi-arch manifest withdocker buildx imagetools create.docker/metadata-action: branch, tag, semver, sha, andlatest(default branch only) tags replace the hand-rolled tag script.Notes for reviewers
