Support executing Dockerfiles and Docker Compose files

[MelbourneDeveloper]

Summary

Dockerfiles and Docker Compose files should be executable from CommandTree.

Details

Users should be able to run Docker-related files directly from the tree:

• Dockerfile: Build the image (e.g., docker build -f <file> .)
• docker-compose.yml: Start services (e.g., docker compose -f <file> up)

This would make it easy to manage container workflows without switching to a terminal.
