This commit adds a new test file, `tests/test_cli.py`, containing unit tests for the `_os_timezone` function in `netsleuth.cli`. The tests cover: - Happy paths (TZ variable, /etc/localtime symlink, /etc/timezone file) - The edge case of an `OSError` exception being thrown when reading the /etc/timezone file.
