Cut v1.15.11b — pin setup-buildx-action@v4.0.0

The v1.15.11 publish failed three times in a row (runs #332/333/334) with identical '400 Bad request' from registry-1.docker.io on the multi-arch buildx layer-blob PUT. Triage on 2026-05-27 confirmed: - Multi-arch buildx push from a developer host: succeeds in 25s (same Hub account, same multi-arch path) - Account / repo / Hub-CDN: all healthy - Last known-good Gitea-runner Hub push: 2026-05-23 ~20:26 UTC (pi-devbox v0.75.5b) — predates docker/setup-buildx-action v4.1.0 by <24h - docker/setup-buildx-action@v4 floats to v4.1.0 (published 2026-05-22 16:00 UTC), bundling a newer buildx/buildkit whose push protocol may trip Hub's CDN URI-length cap on the ~1.4 KB _state query string in resumable-upload PUT URLs. Pinning all nine setup-buildx-action references to @v4.0.0 to test the hypothesis. setup-qemu-action@v3 left floating since QEMU wasn't in the suspected blast radius. If v4.0.0 publishes cleanly we keep the pin and file an upstream buildkit/buildx issue. No source changes — same OPENCODE_VERSION=1.15.11, same Dockerfile.base and Dockerfile.variant. v1.15.11 (original tag) is preserved as a historical marker of the first publish attempt; v1.15.11b becomes the canonical release.

+Container-level rebuild of v1.15.11. The original v1.15.11 release-day publish failed three times in a row (CI runs #332/333/334) with identical `400 Bad request` responses from `registry-1.docker.io` on the buildx layer-blob PUT. Build itself succeeded 30/30 each time; only the multi-arch push failed. Triaged on 2026-05-27 evening:
+
+- **Local multi-arch buildx push from a developer host succeeds in ~25s** — same Hub account, same multi-arch path. Account, repo, and Hub-CDN are all healthy.
+- **Last known-good Gitea Actions Hub push: 2026-05-23 ~20:26 UTC** (`pi-devbox v0.75.5b`). All Gitea-runner-driven pushes since 2026-05-24 have failed identically.
+- **Smoking gun candidate:** `docker/setup-buildx-action@v4` floats to `v4.1.0` (published 2026-05-22 16:00 UTC). Action-resolver caches on the runner appear to have rolled forward to v4.1.0 sometime between the May 23 success and the first May 24 failure. v4.1.0 ships a newer bundled buildx/buildkit which may be using a different push protocol that trips Hub's CDN URI-length cap (the failing `_state` query string is ~1.4 KB).
+
+### Workflow change
+
+- **`.gitea/workflows/docker-publish-split.yml`** — all nine `docker/setup-buildx-action@v4` uses pinned to `@v4.0.0`. `setup-qemu-action@v3` left floating since QEMU wasn't in the suspected blast radius and was working on May 23. If v4.0.0 publishes cleanly we keep the pin and file an upstream buildkit/buildx issue documenting the regression.
+
+No other source changes — same `OPENCODE_VERSION=1.15.11`, same `Dockerfile.base` and `Dockerfile.variant`, same SSH-CM bake, same gitleaks. v1.15.11 (the original tag) is preserved in the repo as a historical marker of the first publish attempt; v1.15.11b is the canonical release.
+
+### v1.15.11

 First release on opencode 1.15.11. Also bakes in four devbox-side fixes accumulated since v1.15.10 (SSH ControlMaster on a writable path, gitleaks added to base, CI resolve-versions hardening, CI cache-hit regression fix). Downstream pi-devbox inherits all of these on its next build against `base-latest`.
