[Enhancement] Optimize Docker Hub integration and image publishing workflow

[Iktahana]

Description: Currently, our Docker Hub support is functional but basic. This issue aims to refine the image publishing pipeline, improve tagging strategies, and ensure our images are optimized for size and security.

Tasks:

[ ] Implement automated builds via GitHub Actions/CI for Docker Hub.

[ ] Adopt a clearer tagging strategy (e.g., latest, v1.x.x, beta).

[ ] Optimize the Dockerfile to reduce image size (multi-stage builds).

[ ] Integrate security vulnerability scanning for all published images.

[ ] Update the Docker Hub repository description and "How to use" instructions.

Expected Outcome: A robust, automated, and secure delivery pipeline for Commander images on Docker Hub.
