Fix: Support hyphens in command-line argument names (#576)

Allow CLI arguments to be specified with hyphens instead of only
underscores. For example, `--proxy-auth-headers` now works in addition
to `--proxy_auth_headers`. This matches the standard convention for
command-line arguments where hyphens are typically preferred over
underscores.

The parser now checks both the original config attribute name and a
hyphenated variant when matching arguments, making the CLI more
intuitive and consistent with typical Unix/Linux command-line tools.
