Attach any sample test data file(s)

Files in folder 1 in my environment, plus
Files in folder 2 in my environment (containing SDTM .json files from the Dataset-JSON release).

If needed I'll add; however, I don't think we need to test with my data as you may want to test with accessible files in your environment.

Attach any output report and/or log file(s)

bash_coreval_examples_sdtm_json_mhungria_Rule0998_2026-03-16_2_wo_vba.xlsx

Expected output

I would expect either of:
a) Processing files from the 2 folders correctly, retrieving all files from folder 1 plus all files from folder 2, providing information to the user if filenames are duplicated and explicitly indicating if any is discarded.
b) Appropriate documentation indicating multiple -d parameters is not allowed.

Any Additional Information

See #1641
