fix: ci GHCR_REPOSITORY env

[seefs001]

Summary by CodeRabbit

• New Features

  • Publish official multi-architecture Docker images (amd64 and arm64).
  • Provide per-architecture tags and combined multi-arch manifests on Docker Hub and GHCR.
  • Introduce alpha image versioning (date + short commit) and publish both alpha and versioned tags.

• Chores

  • Overhauled CI to a two-phase build (per-arch) and manifest creation for faster, more reliable releases.
  • Enabled build caching, provenance, and SBOM generation.
  • Improved Dockerfile to natively support multi-arch builds (OS/ARCH aware).

Walkthrough

Refactors Docker image workflows to per-architecture matrix builds that push single-arch images, then creates and pushes multi-arch manifests to Docker Hub and GHCR. Adds version/tag derivation and repository normalization. Updates Dockerfile to accept TARGETOS/TARGETARCH and set GOOS/GOARCH dynamically.

Changes

Cohort / File(s)	Summary of Changes
Workflow: Matrix per-arch builds + manifest creation .github/workflows/docker-image-alpha.yml, .github/workflows/docker-image-arm64.yml	Replace single push job with matrix build_single_arch (amd64/arm64) and a dependent create_manifests. Add shallow checkout, version/tag derivation, GHCR repo normalization, Buildx setup, switch to docker/build-push-action@v6 with per-arch tags, caching, provenance/SBOM, and imagetools-based multi-arch manifest creation for Docker Hub and GHCR.
Dockerfile: Parametric OS/ARCH Dockerfile	Introduce ARG TARGETOS, ARG TARGETARCH; set ENV GOOS/GOARCH from args with defaults; retain GO111MODULE=on, CGO_ENABLED=0. Enables cross-arch builds driven by build args.

Poem

A rabbit builds on clouds so high,
For amd and arm it bakes a pie. 🥧
Tags aligned, manifests spun,
Hub and GHCR—both are done.
GOOS, GOARCH hop in line,
Multi-arch dreams now ship just fine. 🐇🚀
