feat: add GPU status indicator and device probe

Browse Source 
- GpuEvaluatorFactory probes for CUDA/OpenCL devices at startup
- Status bar shows "GPU : <device name>" (green) or "GPU : None (CPU)" (gray)
- Factory skips GPU evaluator creation entirely when no device found
- Logs actual exception message on failure for debugging
