Subject: fix(console): make Command/BaseCommand methods take &self

The Command trait and Composer's BaseCommand took &mut self, so dispatch
held a borrow_mut on the command's RefCell for the whole call. A command
re-entering itself (e.g. the help command describing itself) then panicked
with "RefCell already borrowed".

All Command/BaseCommand methods now take &self and the command state is
interior-mutable (Cell/RefCell). Shared borrows coexist, so re-entrant
describe paths no longer conflict. Getters that returned references now
return Ref guards; the descriptor describe_* methods take &dyn Command;
mixin accessors return Ref/RefMut.
