Use when the user wants to convert a raw neuroimaging DICOM dataset to BIDS format. Triggers on requests mentioning "DICOM", "BIDS", "dcm2bids", "dcm2niix", or "convert MRI scans". Handles compressed archives (.zip/.tgz/.tar.gz), extensionless DICOMs (DICM magic bytes), multi-session datasets, classifies series (T1w/T2w/FLAIR/DWI/BOLD), runs dcm2bids, and validates output with bids-validator.
