- Added restart_workers command from master to clients for backend switching
- Cluster clients can now restart their workers with different backends (CUDA/ROCm/CPU)
- Added mixed GPU detection - nodes with both CUDA and ROCm show 'Mixed GPU Available' indicator
- Clients with mixed GPUs can switch between CUDA and ROCm backends dynamically
- Updated API endpoint to send restart commands to connected clients
- Clients save driver preferences and restart workers immediately when changed
- Graceful fallback to available backends if requested backend not available
- Visual indicator for nodes capable of backend switching
