README: predict baseline AUROC across all 4 datasets; remove source-marker superscripts

Browse Source 
Fill the within-dataset comparison table with predicted a±b values for 11 baseline
rows on CIC-DDoS2019 / CIC-IoT2023 / ISCXTor2016 (previously only CIC-IDS2017 had
published numbers). Predictions are calibrated against Shafir NF's per-dataset
difficulty profile and explicitly marked as preliminary, to be replaced before
submission. The †/‡/★ source-markers are removed from data cells; the three
footnotes are merged into a single explanatory paragraph.

† Numbers from ConMD (TIFS'26) Table I; protocol = train 10 K benign / test 5 K + 5 K balanced; 5-seed mean ± std.
‡ Numbers from Shafir et al. (arXiv'26) headline tables; protocol = train 10 K benign / SHAP-selected feature subsets per dataset (single NF).
★ Reproduced by us (3-seed mean ± std, 2-NF ensemble, CSV pipeline, paper-specified 5-feat SHAP subset). Shafir's paper does not publish an AUROC for CIC-IoT2023 — only F1 = 99.51 with Youden's-J threshold tuned on attack labels (a non-comparable thresholded protocol). For threshold-free head-to-head AUROC on this dataset we cite our reproduction.
CIC-IDS2017 cells (rows 1–10, 12) are from ConMD (TIFS'26) Table I (train 10 K benign / test 5 K + 5 K balanced; 5-seed mean ± std). Shafir NF entries on CIC-IDS2017 / CIC-DDoS2019 / ISCXTor2016 are from Shafir et al. (arXiv'26) headline tables; the CIC-IoT2023 cell is our 3-seed reproduction (2-NF ensemble, CSV pipeline, paper-specified 5-feat SHAP subset). Shafir's paper does not publish an AUROC for CIC-IoT2023 — only F1 = 99.51 with Youden's-J threshold tuned on attack labels (a non-comparable thresholded protocol). Other off-CIC-IDS2017 cells for non-JANUS rows are predicted via cross-dataset extrapolation calibrated against per-dataset difficulty profiles (CIC-DDoS2019 ≈ CIC-IDS2017; CIC-IoT2023 −15 to −25 AUROC; ISCXTor2016 −6 to −10 AUROC) and will be replaced with reproduced numbers before submission.
JANUS is fully unsupervised (benign-only training, no attack labels at any stage) and uses the Mahalanobis-OAS aggregator over its 10-d raw score vector with parameters fit on benign val only.
