The recipient picker listed every contact, but a courier message is a
direct message — and a DM to a repeater, room, or sensor is meaningless.
Filter the recipient list to companions (an untyped contact gets the
benefit of the doubt), and open it sorted A→Z by name instead of by
heard, with heard/packets/key still a Ctrl+arrow away.
Fold the rule the chat picker already applied inline into one shared
predicate, is_direct_messageable(node_type), so "DMs go to companions
only" is enforced in a single place and both pickers speak it.
