Feature Request: Inbound Redeploy Webhook for Docker Image Services

Hi Zeabur Team,

I'm a big fan of Zeabur and currently deploying my backend service to my own VPS (Tencent Cloud) via Zeabur. It's been fantastic for keeping my hosting costs low.

To optimize memory usage and avoid Out-of-Memory (OOM) build crashes on my 2GB RAM VPS, I recently switched my Node.js Express backend to a Docker-based deployment:

1. GitHub Actions compiles the TypeScript code and pushes a production-pruned Docker image to GitHub Container Registry (GHCR).
2. Zeabur pulls and runs this image directly on my VPS (which brought idle memory usage down by over 80%!).

However, I've run into an automation bottleneck. Every time GitHub Actions pushes a new latest tag to GHCR, Zeabur does not auto-detect the update. I have to manually log in to the Zeabur dashboard and click the "Restart" button to pull the new version.

Could you add support for automatic redeployment of Docker Image services?

Either of these approaches would be amazing:

1. A "Watch Registry / Auto Deploy" toggle in the service settings (similar to how you auto-deploy Git repository pushes) that polls the registry and pulls the new image when the digest changes.
2. Or, an inbound Redeploy Webhook URL that we can trigger at the end of our CI/CD pipelines (e.g. via curl in GitHub Actions).

This would make Docker-based deployments on custom servers 100% automated and elegant.

Thank you for building such an awesome platform!

Best regards,
