Make frontend GPU displays vendor-neutral (AMD compatible)

Updated 3 components to display AMD GPU information correctly:

1. AgentSandboxes.tsx:
   - 'NVIDIA GPU' → 'GPU' (fallback text)
   - 'nvidia-smi:' → 'GPU query:' (query timing label)

2. RunnerSummary.tsx:
   - GPU name parsing: Strip NVIDIA/AMD/Intel/Radeon prefixes
   - Tooltip: 'CUDA:' → 'SDK:' (shows 'CUDA 12.9' or 'ROCm 6.4')
   - cuda_version → sdk_version field

3. FloatingRunnerState.tsx:
   - GPU name parsing: Strip NVIDIA/AMD/Intel/Radeon prefixes
   - Tooltip: 'CUDA:' → 'SDK:' (vendor-neutral)
   - cuda_version → sdk_version field

Now displays correctly for:
- NVIDIA GPUs: "H100 • Driver: 550.54.15 • SDK: CUDA 12.4"
- AMD GPUs: "RX 7900 XTX • Driver: 6.4.4 • SDK: ROCm 6.4"
