fix: restore superlatives methods, fix event update rebuild, remove dead method

- Restore subscribeSuperlatives/unsubscribeSuperlatives/onSuperlativesUpdate
  on SocketClient (lost during Task 5 refactor)
- Fix EventsFeed.updateEvent to rebuild entire element when LLM narration
  arrives (names may be in different positions)
- Remove dead setFollowedEntity method from GameLoop (replaced by
  SocketServer.rebuildFollowedEntityIds)
