Detailed Description

LorentzEliminator: 2x2 operator B of the Schur scheme for implicit velocity elimination.

Encodes B = [[1, -w], [w, 1]] and its inverse B^{-1} = (1/det)*[[1, w], [-w, 1]], with w = theta * dt * B_z and det(B) = 1 + w^2 (always > 0: B invertible for any real w).

POD struct, zero allocation, trivially copyable. All accessors POPS_HD. No std:: call: device-safe under Kokkos/CUDA/HIP without restriction.
