feat(researcher): DCE-MRI BBB permeability bridge + drug-dose adjuster

feat(eeg,frontend): EEG fusion-flow test + Streamlit EEG form + real-artifact sanity

feat(models): EEG classifier loader + predict (stub-able for hackathon demo)

test(models): real-artifact sanity for MRI DL 2D (skips when absent)

feat(models): selector dispatch for volumetric vs 2D MRI models

feat(models): add 2D resnet18 4-class Alzheimer's MRI inference module

test(mri/model): drop redundant caplog.at_level (direct handler attach is the actual mechanism)

fix(mri/model): warn when label_names length != model output dim (was silent override)
