Remove unused dispose method and settings subscription from BaseAIClass. Update SettingsService to track which settings changed and notify subscribers with specific changed keys. Components now only react to relevant setting changes. Export RegisterAiProvider and call it when AI provider settings change to ensure provider is re-registered with new configuration.
Replace object-based subscription tracking with token-based system to prevent memory leaks. Add dispose() method to BaseAIClass and ensure all components properly unsubscribe in onDestroy. Update SettingsService.subscribeToSettingsChanged to return subscription token instead of requiring subscriber object parameter.
