Fix clw-gpu-limit-exceeded: OpenClaw GPU resource limit exceeded

1. Symptoms

The clw-gpu-limit-exceeded error in OpenClaw manifests during kernel execution or resource allocation on GPU devices. OpenClaw, a high-level C++ wrapper for OpenCL, throws this error when the GPU’s hardware limits are surpassed, such as total global memory, local memory per compute unit, or maximum concurrent work-items.

Typical symptoms include:

Error: clw-gpu-limit-exceeded
GPU device 'NVIDIA GeForce RTX 3080' exceeded resource limits.
Available global memory: 10 GB
Requested: 12 GB for buffers + kernels
Aborting kernel enqueue on queue 0x7f8b2c001230

CLW_ERROR_GPU_LIMIT_EXCEEDED: clEnqueueNDRangeKernel failed with CL_OUT_OF_RESOURCES (-5)
Context: queue.submit(kernel, global_work_size=[1024,1024], local_work_size=[16,16])

Programs may hang indefinitely, crash with segmentation faults, or fallback to CPU execution if multi-device support is enabled. GPU utilization spikes to 100% before failure, visible via nvidia-smi or rocm-smi:
