kaist-snubh-barreleye: v2 cohort update (replace S11/S29 with S36/S37, fix S16 label, update data card)

Removed (4 files): S11_D1/D2, S29_D1/D2

Added (4 files): S36_D1/D2 (BI-RADS 2, benign, follow-up confirmed) and S37_D1/D2 (BI-RADS 4c, biopsy-proven IDC)

Replaced (2 files): S16_D1/D2 — metadata.annotations.label corrected from malignant to benign (pathology: atypical ductal hyperplasia). Channel data and all other fields are unchanged.

README.md: subject-ID range, age / BI-RADS / lesion-size / histopathology tables and the benign–malignant split updated for the revised cohort.
