• Android setup is clearer. The app now proactively explains the
  required All files access permission, rechecks it after returning from
  Android settings, and documents the common Android upload/install issues
  in the FAQ.
• Engine startup diagnostics are easier to find. If the local engine
  fails to start, PS5 Upload now records the reason in the app log and
  status tooltip instead of only showing a red engine dot.
• Release and docs cleanup. Updated stale release workflow references,
  marked the Android feasibility doc as historical, and tightened ignored
  Android build artifacts.
