What is new

1.3.3: cleaner Organized Library and more reliable startup

Verified-content duplicate protection now works during both safe-copy planning and actual execution, helping prevent redundant MIDI/KAR copies from different source paths.

More predictable large-library analysis through bounded candidate-result processing, including Stop Safely safeguards.

A more reliable splashscreen that stays visible when clicked; Linux device identification is more stable across Python runtime changes.

This maintenance release builds on the previous threading and Organizer improvements. Different MIDI performances can still be kept separately.
