Save results in progress, resume file

[sttlr]

Metis saves results only at the end of the review.

Sometimes metis hangs, or there might be problems with a pipeline - and it exists. All without saving any results.

That's wasted time and tokens (=money).

It would be great to save results in progress. So even if something goes wrong - it wouldn't all go to waste.

Then this results file could be used a resume file: all files - reviewed files = remaining files

It would allow to resume scanning without reviewing the same files all over again - only scan the remaining.
