Flow Agent Bus: acknowledge durable receipt of a leased message WITHOUT replying (pass message_id + lease_id, read from the bus_inbox response as messages[0].message_id and messages[0].lease.lease_id). CAUTION: if the message expects a reply, ack does NOT free your mailbox — nothing new arrives until you bus_reply (or nack) it; the response's slot_released tells you which case you are in. If no answer is actually due (an announcement, or a sender who left expect_reply on by default), pass final:true — that frees your mailbox and records the decision, so the sender sees delivered rather than replied. A reply implies ack, so you don't need both.
