Client half of the per-chat notification preference — DetailBar gets a bell
dropdown (every end of turn / only when input is needed / none), a global
useChatNotifications hook holds one connection to /api/chat/notify/ws for
the whole session so a background chat can still ring the bell and fire a
browser Notification, and the session list shows a badge on any row set to
notify. The server side (schema, the notify-delivery socket, the sidecar
signal at turn-end/plan-gate/question-gate) landed already in 5cba1b65,
swept in from a concurrent session sharing this working tree.
