feat: Add mutation validation and demonstration scripts #13

	# GitHub Action: Build & Push Docker image to Docker Hub
	# Requires two repository secrets:
	# DOCKERHUB_USERNAME – your Docker Hub username (e.g. xpert123)
	# DOCKERHUB_TOKEN – a Personal Access Token with "write:push" scope
	#
	# On every push to main (or when Docker-related files change) this will
	# build the image and push the tag `latest`.
	# Adjust the `tags:` value if you need versioned tags.
