Lucas Berger d03e79cc7f feat(05): add update acknowledgment and pull error handling 
1. Send "Updating <container>..." message immediately when update starts
   so user knows the command was received during long image pulls

2. Check pull response for rate limiting and other errors before
   continuing with update. Errors like "toomanyrequests" now show
   a proper error message instead of silently failing to update.
