feat(console): implement get_command_name_before_binding via input clone

Replace the todo!() stub with the real Symfony logic: clone the input,
bind it against the application definition (ignoring binding errors), and
read the first argument so the command name is detected even when global
options precede it.

Add a dup() method to InputInterface to model PHP's clone, derive Clone on
the input types, and treat InvalidArgument/InvalidOption/MissingInput as
ignorable ExceptionInterface errors during the pre-binding probe.
