Subject: refactor(command): share Input/OutputInterface via Rc<RefCell>

Convert InputInterface and OutputInterface parameters from &dyn/&mut dyn
references to Rc<RefCell<dyn ...>> shared ownership across the command,
console, and IO layers, matching the Phase C shared-ownership approach
already used for IOInterface.
