Feature Request: Track Deleted Videos

[apiweb]

Describe the solution you'd like

TubeSync could add a feature to check video status during agent runs on a channel or playlist. If a video was previously downloaded but is now deleted on YouTube, TubeSync could label or flag it as "Deleted On Origin".

This feature will be particularly useful when (for example) we add a "Watch Later" list or playlist with videos from multiple channels. YouTube informs us of deleted videos without specifying which ones. With this feature, TubeSync will flag or label the deleted videos. And we can identify quickly if the owner deleted the video.

Additional context

Screenshot from a video deleted from the playlist, we can't identify which video was deleted.
