[Bug] Docker image tag 2026.8.1 reports internal version 2026.7.1-2

Summary

The Docker image published under tag coollabsio/openclaw:2026.8.1 contains an internal binary that reports version 2026.7.1-2 instead of 2026.8.1. Confirmed the same digest is published under both Docker Hub and GHCR, ruling out any local caching or pull issue.

Steps to reproduce

1. Deploy coollabsio/openclaw:2026.8.1 via Docker (Coolify on a VPS)
2. Exec into the running container and run openclaw --version

Expected behavior

openclaw --version should report 2026.8.1

Actual behavior

openclaw --version

OpenClaw 2026.7.1-2 (0790d9f)

Evidence

• Image digest (verified identical on Docker Hub and GHCR): sha256:09e466ce490ff47500ce06b6e078a9f48ce443377eefc4bb6710a91e513c9276
• GHCR package page confirms this digest under tag 2026.8.1, marked "Latest"
• Forced a fresh pull after removing the local image (docker rmi + docker pull) — same digest returned, ruling out local caching
• The gateway logs show config warnings consistent with the old runtime:

plugins: plugin deepseek: plugin requires plugin API >=2026.8.1, but this host is 2026.7.1-2; skipping discovery

• Attempting to update from the Control UI ("Actualizar ahora") fails with:

Update skipped: managed-service-handoff-unavailable

and the gateway logs show:

update.run completed ... restartReason=update.run status=skipped

Environment

• Deployment: Docker container via Coolify on a self-hosted VPS
• Image: coollabsio/openclaw:2026.8.1
