CLI: vyasa sync

                                                                                
 Usage: vyasa sync [OPTIONS]                                                
                                                                                
 Share the hidden project-state timeline with 'origin'.                         
                                                                                
 Fetch → merge → push on refs/vyasa/state. Disjoint edits braid                 
 automatically; same-file collisions abort with the file list                   
 (exit 2) until you re-run with --ours. With --with-code the current            
 branch HEAD is pushed in the same round-trip.
