Bump opencode to 1.14.31 and split multi-arch publish across runners

The v1.14.30b publish failed on both variants with 'No space left on device' — arm64 QEMU-emulated layers were stored alongside amd64 on the same ~40 GB runner, and the mempalace-toolkit bake-in from v1.14.30b tipped peak disk over the edge during the nodejs dpkg unpack and the git-lfs layer export. Refactor docker-publish.yml to the canonical push-by-digest + manifest-merge pattern: smoke test (amd64) runs on its own runner, each (variant x arch) push target runs on its own fresh runner with outputs=type=image,push-by-digest=true,push=true (no local image store), then a tiny merge job assembles the multi-arch manifest with docker buildx imagetools create from digest artifacts. Per-runner disk peak is roughly one-quarter of the old single-job peak. The four Docker Hub tags per release are unchanged. As a bonus, amd64 and arm64 now build in parallel. No image-level changes beyond the opencode bump.

+Bump opencode to 1.14.31.

+**CI infrastructure: split multi-arch publish across separate runners.**
+
+- **Fix:** The `publish` workflow exhausted runner disk space on `v1.14.30b` and would have hit the same wall on any subsequent release. Both variants built both architectures on a single `catthehacker/ubuntu:act-latest` container with ~40 GB of shared overlay space, and the peak disk footprint during the nodejs dpkg unpack / git-lfs layer export pushed it over the edge (`No space left on device`). The mempalace-toolkit bake-in from v1.14.30b added the final straw; the underlying issue is that QEMU-emulated arm64 layers were stored alongside the amd64 build on the same runner.
+  - `docker-publish.yml` refactored to the canonical `push-by-digest` + manifest-merge pattern: smoke test (amd64) runs on its own runner, each `(variant × arch)` push target runs on its own fresh runner with `outputs: type=image,...,push-by-digest=true,push=true` (no local image store), then a tiny merge job assembles the multi-arch manifest with `docker buildx imagetools create` from digest artifacts.
+  - Per-runner disk peak is now roughly one-quarter of the old single-job peak. The four Docker Hub tags produced per release (`vX.Y.Z[n]`, `latest`, `vX.Y.Z[n]-omos`, `latest-omos`) are unchanged.
+  - Also parallelizes the amd64 and arm64 builds, so wall-clock time for a release should drop noticeably despite the added merge hop.
