Support versioned Docker image tags for components like opensandbox-server and opensandbox-controller

Hi OpenSandbox community,

I have a question about the Docker image release/tagging strategy for opensandbox/server and opensandbox/controller.

It looks like newer builds/releases are being pushed to the latest Docker tag, but a corresponding immutable/versioned tag is not always published.

This makes it difficult for us to lock our deployment to a specific version. Using latest means that the image can change underneath us, which makes deployments less reproducible and makes controlled upgrades/rollbacks harder.

Would it be possible for each release to publish both tags, for example:

opensandbox/server:v0.x.x
opensandbox/server:latest

and similarly for the controller:

opensandbox/controller:v0.x.x
opensandbox/controller:latest

That way, users who want automatic updates can use latest, while production deployments can pin to a specific version.

Is there a reason the current release process sometimes publishes only/primarily to latest, or is versioned tagging something that could be added to the release workflow?
