Subject: [PATCH] Fix inconsistent argument parsing behavior across Python
 versions

This change modifies the argument parser to use `parse_intermixed_args()` instead of `parse_known_args()` to ensure consistent behavior across Python versions. This addresses issue #1838 where the position of optional flags like `-v` affects argument parsing differently depending on the Python version.

The fix ensures that optional arguments can be placed before or after positional arguments consistently across all supported Python versions (3.11, 3.12, and 3.13+).
