🤖 You can now mute a chat or a person. Mute a chat from its ⋮ menu — no
notifications, no unread dot, and messages keep arriving quietly. Mute a
person from their profile card or a long-press on their message — their
messages fold into a small "Muted message" stub you can tap to read, and they
never notify you. Muting is private: the other person isn't told, and who
you've muted is sealed on your devices — the server can't read it either.
