Previously POST /v1/messages returned the message_queue row id as `messageId`. Topic posts ARE durable (in topic_message); the queue entry drains on delivery. Pasting that id into `--reply-to` failed because the broker validates parents against topic_message, not the queue. Now `messageId` aliases `historyId` for topic posts; both `historyId` and `queueId` remain available as explicit fields. Roadmap and CLI README updated with v0.3.1 reply-to + v0.3.2 multi-session entries.
