Add CLI entrypoint test and mark slow tests #23

[AdityaGupta716]

Describe your changes

Added a test for the actual installed CLI entry point by running it as a subprocess with --help. This catches import/dependency errors (like a missing psutil dependency) that would not be caught by calling the Python function directly.

Marked the existing test_call as @pytest.mark.slow since it requires network access and AWS credentials to run. Registered the slow mark in pyproject.toml to avoid pytest warnings about unknown marks.
