Pull Request Overview

This PR adds comprehensive CI/CD infrastructure using GitHub Actions for automated building, testing, and deployment of the WFR DAQ system. It includes automated Docker image building to GitHub Container Registry, code quality checks, and removes old development files.

• Adds three GitHub Actions workflows for building/testing, code quality checks, and deployment
• Creates a helper script to pull pre-built Docker images from the registry
• Updates documentation with detailed CI/CD pipeline information
• Removes obsolete development files (HTML templates, Python scripts, build files, DBC files)

The script is missing a proper shebang error handling pattern. Consider adding set -euo pipefail after the shebang for more robust error handling, which will exit on any error, undefined variables, and pipe failures.

The workflow only triggers on the 'deploy' branch, but based on the documentation in README.md which mentions 'main'/'develop' branches, this seems inconsistent. Consider aligning the trigger branches with the documented workflow or updating the documentation.

Both tag assignments write to the same 'tags' output key, causing the second assignment to overwrite the first. The Docker build will only use the SHA tag, not the 'latest' tag. Use different output keys or combine them into a multi-line value.
