Add Unit Tests for src/utils.py

[abduznik]

Utility functions in src/utils.py currently lack automated tests.

Instructions:

1. Create a new test file ests/test_utils.py.
2. Implement unit tests for
   un_shell, parse_json_response, and check_gh_auth.
3. Use pytest and unittest.mock to mock subprocesses and external CLI calls to ensure tests are isolated and reliable.

Hi! I'd like to take a look at this. I'm new to the project but I've fixed similar issues before. I'll submit a PR shortly.
