refactor(command): replace composer_full_mut with shared composer_full

The compiler confirms none of the call sites invoke a &mut self method
on the returned Composer, so the exclusive RefMut borrow was never
needed and only risked borrow check conflict. Switch every site to the
shared composer_full borrow and drop the now-dead composer_full_mut
helper.
