* Re-enabled OpenMP. 1. Batch spectral derivatives (Chebyshev & Fourier) via precomputed matrices: Chebyshev/Fourier transforms and derivatives are precomputed as explicit physical-space operator matrices. Batch DGEMM now applies to entire tensor fields, mathematically identical to original per-line transforms but vastly faster. 2. Gauss-Seidel relaxation & tridiagonal solver workspace reuse: Per-thread reusable workspaces replace per-call heap new/delete in all tridiagonal and relaxation routines. 3. Efficient OpenMP multithreading throughout relaxation/deriv: relax_omp and friends parallelize over grouped lines/planes, maximizing threading efficiency and memory independence.
