ci: publish multi-arch Odysseus image to GHCR (dev + stable) (#3423)

* ci: build and publish multi-arch Odysseus image to GHCR Push to main publishes :latest and :X.Y.Z; push to dev publishes :dev and an immutable :X.Y.Z-dev.<sha>. Multi-arch (linux/amd64 + linux/arm64) via per-arch native runners building by digest, merged into one manifest list. Uses the in-repo GITHUB_TOKEN (packages: write), actions pinned by SHA. * ci(docker): pin actions to latest major releases checkout v6.0.3 (matches the PR-checks workflow), setup-buildx v4.1.0, login v4.2.0, build-push v7.2.0, metadata v6.1.0, upload-artifact v7.0.1, download-artifact v8.0.1 — all by commit SHA.

+# Build the Odysseus image and publish to GHCR.
+#   push to main -> :latest, :X.Y.Z            (curated release; main is fast-forwarded at releases)
+#   push to dev  -> :dev,    :X.Y.Z-dev.<sha>  (rolling dev + an immutable, traceable pin)
+# Multi-arch (linux/amd64 + linux/arm64): each arch builds on its own native
+# runner and pushes by digest, then a merge job stitches the digests into one
+# manifest list and applies the tags (faster + cleaner than QEMU emulation).
+# Registry: ghcr.io/<owner>/<repo>.
