Every avatar in the app (chat messages, room member list, your own avatar in the top bar/profile, the admin user list, the room-invite search) now shows a green/red presence dot. Also adds a global "Appear offline" toggle in the account menu, letting a user lurk in a room undetected -- it overrides the real connection state everywhere, not per-room. Backend: new GlobalPresence (backend/app/ws/global_presence.py), a cross-instance Redis-backed connection tracker parallel to the existing per-room Presence, incremented/decremented on WS connect/ disconnect. A new users.appear_offline column (migration f0f6e494454a) always wins over actual connection state when computing displayed status. RoomMemberRead gained a computed `status` field; add_member/change_member_role/list_room_members all compute it via a shared _member_status() helper. Connect/disconnect and profile updates (display_name, avatar, appear_offline) all broadcast member_updated to every room the user belongs to, reusing the broadcast infrastructure from the earlier avatar-staleness fix, so chat surfaces update live with no new WS envelope type needed. A new GET /api/users/online gives the admin list and user-search a snapshot (deliberately not live -- see backend/app/routers/users.py) for surfaces where "accurate as of page load" is good enough. Frontend: UserAvatar renders an optional status dot; every call site threads status/appear_offline through from whichever data source it already has (room members, the current user, or the new online-ids snapshot for admin/search). 4 new backend tests (backend/tests/test_presence.py); existing broadcast-adjacent WS tests updated to tolerate the new member_updated noise on connect. Verified end-to-end in the browser with two real users: presence dot flips live on connect/disconnect via the existing room-broadcast channel, and the lurk toggle correctly forces offline while still connected.
