  fetchUserNotesNIP65 in client.ts; profile notes fetched via the
  author's write relays; "Publish relay list to Nostr" button in
  Settings (kind 10002)

- Notifications: new store (notifications.ts) + NotificationsView;
  🔔 sidebar nav item with unread badge; DM nav item also shows
  unread conversation count; badges clear on open/select

- Keyboard shortcuts: useKeyboardShortcuts hook + HelpModal;
  n=compose, /=search, j/k=feed nav with ring highlight,
  Esc=back, ?=help overlay
