Install nvidia pip packages for CUDA 12 runtime DLLs (no full toolkit needed): nvidia-cuda-nvrtc-cu12, nvidia-cuda-runtime-cu12, nvidia-curand-cu12, nvidia-cublas-cu12 Add _register_nvidia_dlls() in backtest_gpu.py that auto-discovers and registers nvidia package DLL directories (site-packages/nvidia/*/bin/) via os.add_dll_directory() before CuPy is imported. Suppresses the spurious "CUDA path could not be detected" warning from cupy._environment. Backend line now reads: CuPy 14.0.1 (RTX GPU) Benchmark: scoring pass on 100k bars — NumPy 1.1ms vs CuPy 0.18ms = 6.3x. Results are identical to CPU path (deterministic).
