Remove duplicate tracks from playlists in one action

The submitted context

Large playlists can accumulate duplicate tracks, including separate releases of effectively the same recording. Spotify may warn while adding an exact duplicate, but people report that merged playlists can still contain repeated songs and currently use external deduplication tools. Spotify's playlist help documents removing tracks individually, not a review-first duplicate audit. Please add a built-in Find duplicates view for playlists and Liked Songs. It should separate exact track IDs from likely duplicate recordings, let listeners preview every proposed change, and allow them to choose which copy to retain. Nothing should be removed automatically. These two community posts are qualitative workflow examples, not representative demand estimates.
