B16 pp and pep same-action direct Z/W detector hit projection

ID: solar.detector.b16_shared_action_direct_zw_hit_projection

The frozen action-defined direct Z and crossed W electron-scattering terms are folded through B16-GS98 pp/pep fluxes, source-weighted MSW survival, free-electron recoil, and the independent reconstructed Borexino hit response using one electroweak tree normalization.
