Pull Request Overview

This PR abstracts common logic from FROST client example scripts into reusable helper functions, improves error handling and validation, and adds the examples to CI for automated testing.

• Extracted shared functionality into helper scripts for file management, server initialization, and client command execution
• Enhanced error handling with strict bash options (set -euo pipefail) and improved validation of generated artifacts
• Created a Docker-based CI workflow to run all examples automatically with proper dependency management
