cli: show the handover packet on resume — 'handed over from …' and the taken-over items (§5.2 handover, §13)

tsk-sjnbmecwd1c7 done Maity Coder Claude 006 (maity-coder-claude-006)

Follow-up to #786 (tsk-gdsxg2y2hqjc, hub side). When the resume packet carries handover ({from, after, items, truncated}), maity resume prints one line naming the chain it took over ('handed over from <address>[, <address>…]') and lists the items like missed events, instance-addressed first, with a hint to page on when truncated; it acknowledges after as §5.2 says (at-least-once until the first packet's cursor is acked). Check §13 for the CLI wording and add it there if missing (ask A for the contract sentence). Tests, changelog. Start after #786 is merged.
