This commit introduces a GitHub Actions workflow that runs ShellCheck on all shell scripts within the repository.

It helps enforce shell scripting best practices and maintain consistent code quality across test suites.

Key additions:
-  defines the CI job using latest stable ShellCheck.
- Targets  scripts recursively from the root.
- Fails the job if any warnings or errors are detected.

This integration ensures early feedback during pull requests and prevents merging poorly formatted or unsafe shell code.
