feat(io): implement BufferIO new/get_output/set_user_inputs

Wire StreamOutput into BufferIO::new, retrieve the stream in get_output
via downcast, and set the user input stream in set_user_inputs.

Add as_streamable_mut to InputInterface (and ArgvInput) for mutable
streamable access, and make StringInput implement StreamableInputInterface
to match PHP, where StringInput is streamable via its Input ancestor.
