/**
 * main_gpu_sycl.cpp — SYCL/oneAPI GPU-accelerated entry point for Q3.
 *
 * Links the SYCL backend factories (device, oneMKL BLAS/LAPACK, oneMKL DFT)
 * and delegates the shared entry-point flow to cli::run_gpu_entry_point().
 *
 * Usage: q3_gpu_sycl <input_file> [--log-level <level>] [--precision double|mixed]
