#2: a message arriving in the currently-OPEN chat produced no notification
when the app was minimized. onChatMessage marked the open chat read even
while document.hidden, which fired a notif-clear that closed the very
notification the service worker had just shown. Now the open chat is only
marked read while visible; markOpenChatRead() catches up on focus/visibility
return, and a message received while hidden stays unread with its alert intact.
#3: reacting to a message fired no notification. The react route only pushed
over the live socket (nothing for a closed app) and the client added a silent
bell entry. Now the server sends a native/web push to the message owner, and
onChatReaction pings + shows an OS/in-page popup (unless you're viewing that chat).
