feat: matrix ci

[seefs001]

Summary by CodeRabbit

• New Features
  • Publish native amd64 and arm64 images.
  • Provide multi-arch manifests so “latest”/“alpha” and versioned tags pull the right architecture.
  • Deliver images to both Docker Hub and GHCR with per-arch and multi-arch tags.
• Chores
  • Streamlined build pipeline with native multi-arch builds and manifest creation.
  • Improved tagging consistency and version handling.
  • Added build caching and refined image metadata (labels).

Walkthrough

Refactors Docker image workflows to use a matrix for native amd64/arm64 single-arch builds, then creates multi-arch manifests for Docker Hub and GHCR on tag refs. Adjusts version/tag resolution, login steps, and Docker metadata. Updates Dockerfile to use TARGETOS/TARGETARCH ARGs with corresponding GOOS/GOARCH ENV for multi-arch builds.

Changes

Cohort / File(s)	Summary
CI workflows: matrix single-arch builds + multi-arch manifests \.github/workflows/docker-image-alpha.yml, \.github/workflows/docker-image-arm64.yml	Replace single job with matrix-based per-arch builds (amd64, arm64) using native runners; shallow checkout; revised version/tag resolution; explicit Buildx setup; GHCR login naming; metadata limited to labels; build-and-push per-arch to Docker Hub and GHCR with cache; new job creates/pushes multi-arch manifests (alpha/version and latest where applicable) for both registries.
Dockerfile multi-arch ARG/ENV adjustments Dockerfile	Introduce ARG TARGETOS/TARGETARCH and set GOOS/GOARCH via ENV; explicitly set GO111MODULE=on and CGO_ENABLED=0 in builder stage; remove prior combined ENV block; no change to build steps beyond environment sourcing.

Poem

I thump my paws on silicon ground,
Two arches hop—now side by side bound.
Tags sprout like clover, crisp and light,
Manifests weave the streams just right.
ARGs and ENVs in tidy rows—
A rabbit nods: ship it goes! 🐇🚢
