Subject: The tap-a-bubble action sheet works in DMs too: reactions + Reply +
 Copy (no Delete — a gift-wrapped DM can't be retracted from the peer's
 relays). DM reactions ride the kind-7-in-a-gift-wrap shape 0xchat uses
 (makeDMReaction in dm.js), sent to the peer and echoed to our own inbox so
 other devices fold them in; inbound kind-7 rumors land in dmReacts keyed by
 the reacted message's id — no thread lookup, so a reaction arriving before
 its message still sticks. Replies e-tag the quoted kind-14 (makeDMRumor grew
 extraTags) and render the same accent-bar quote as community chat; the
 composer gets the same replying-to bar. Chips are joinable and your own
 reaction is highlighted/replaceable, all optimistic with rollback. Round-trip
 verified: reply and reaction rumors wrap/unwrap with tags intact
