Leverage duplication for files created by "neural restore"

Is your feature request related to a problem? Please describe.

The new files created by the neural restore module appear as separate entities in the film roll despite being logically the duplicates of the original file. Comparing the results between them becomes clunky and has you search the collection. Their import time to the collection also changes which disrupts the workflow where you have your collection sorted by "import time". The new files aren't grouped together with the original despite logically belonging to the same group. Navigating multiple similar looking files (indistinguishable by the thumbnail) created by the module becomes clunky, it's difficult to tell which file belongs to which original and it takes a lot of time to see what tags/culling/etc has been applied to the original.

Describe the solution you'd like

Have the new files appear as duplicates to the original file.

Alternatives

Additional context

Start by locating the neural restore module and tracing how it creates and imports new files into the film roll. Check the existing duplicate and grouping behavior before deciding where the integration belongs. Done means restored files appear as duplicates of their originals, remain grouped with them, and preserve the expected collection workflow.
