PSMinIO Developer eddbfee192 Fix critical zip flushing issues and add Ctrl+C cancellation support ...

� CRITICAL FIXES:

✅ PROPER DISK FLUSHING:
  • Added _outputStream.Flush() calls to force data to disk
  • Hybrid flushing: 5MB threshold OR 1-second intervals
  • FileStream.Flush(true) for OS-level disk sync
  • Zip files now grow in real-time during processing
  • Fixed 0KB file issue - data now visible immediately

✅ CTRL+C CANCELLATION SUPPORT:
  • Console.CancelKeyPress event handler registration
  • Graceful cancellation with partial file preservation
  • ThrowIfCancelled() checks throughout processing loops
  • Emergency flush and archive completion on cancellation
  • Prevents process termination - preserves partial progress

✅ PERFORMANCE IMPROVEMENTS:
  • Reduced flush threshold from 10MB to 5MB for more frequent updates
  • Time-based flushing every 1 second for better responsiveness
  • Cancellation checks before each file and during buffer writes
  • Proper cleanup in Dispose() method with error handling

✅ RELIABILITY ENHANCEMENTS:
  • CancellationTokenSource for proper async cancellation
  • Volatile _isCancelled flag for thread safety
  • Exception handling during emergency cleanup
  • Console.CancelKeyPress handler removal in Dispose()

� RESULTS:
  • Zip files now show real-time size growth during processing
  • Ctrl+C preserves partial zip file instead of requiring process kill
  • Better performance monitoring with visible progress
  • Robust error handling and cleanup on cancellation

No more 0KB files or slow performance issues!
