Added a test case `test_refresh_netsets_setup_dir` to `tests/test_reputation.py` to ensure that the `setup_dir` nested function in `refresh_netsets` creates the required cache directory.
The test utilizes `unittest.mock.patch` to spy on `pathlib.Path.mkdir`, verifying that the function is called with `parents=True, exist_ok=True`. By setting the mock's `side_effect` to the original `mkdir` function, we ensure side-effects still execute securely, without causing issues if the test suite is run concurrently. All tests pass successfully and test coverage is extended.

_default_gateway() took whichever 0.0.0.0 line route print printed first,
not the one Windows actually uses (lowest metric). With a VPN adapter
installed (Radmin VPN, Tailscale, ...) its default-ish route can print
before the real one. Verified live: was reporting Radmin VPN's 26.0.0.1
while Ethernet (the interface actually carrying traffic, confirmed via
primary_interface_ip()) has gateway 192.168.3.1; now reports that correctly.
Parsing extracted into pure _parse_windows_default_gateway(), tested against
a captured multi-adapter route print sample.
