Merge the Weekly Counts

Every week, a script saves how often certain words appeared in your notes, as a JSON file holding one dictionary:

1{"data": 3, "model": 1}

Write merge_counts(paths, out_path, min_count) that:

1. reads every JSON file listed in paths, in order
2. adds the counts together, word by word (a word missing from a file counts as 0 there)
3. keeps only words whose total is at least min_count
4. saves the result to out_path with json.dump
5. reads out_path back and returns what it read

If paths is empty, or no word reaches min_count, save and return an empty dictionary. The starter code creates week1.json to week4.json. Keep those lines.
