refactor(io): introduce IoInterface trait mirroring Composer IOInterface

Add an `IoInterface` trait in mozart-core::console that mirrors
`\Composer\IO\IOInterface`, implement it for `Console`, and switch
commands, the auditor, and the suggested-packages reporter to accept
the abstracted IO (typically `Arc<Mutex<Box<dyn IoInterface>>>` at the
command boundary, `&dyn IoInterface` deeper down) instead of
`&Console`. The console_writeln\!/write\! macros now go through
`IoInterface::verbosity()` via the lock so any implementor works.
