• Running several PS5s hard at once won't crash a console. When work
  overlapped on one console — reading its live temperature while a package was
  installing, or registering a game on one PS5 while another was mid-install —
  the helper's low-level kernel operations could collide and, in the worst
  case, black-screen and restart the console. Those operations are now
  serialized internally, so heavy concurrent use across consoles stays stable.
  Verified on real hardware (PS5 and PS5 Pro) under a thousand-plus
  concurrent operations.
• One busy console no longer freezes the app for the others. A slow or
  very large upload (especially from a network drive) used to be able to stall
  the desktop engine for every connected console at once. Each console's
  work is now handled independently, so a busy PS5 keeps to itself.
• The Upload screen always shows the right console. Switching tabs mid-
  upload now correctly shows each console's own progress, and the "stay awake"
  and folder-comparison helpers follow the console you're actually uploading
  to. Switching consoles also clears the previous console's game list
  immediately, so an action can never land on the wrong PS5.
