Fix clw-gpu-not-found: OpenClaw fails to detect compatible GPU device

1. Symptoms

The clw-gpu-not-found error in OpenClaw manifests when the library attempts to initialize an OpenCL context targeting a GPU device but fails to detect any compatible hardware. This typically halts program execution during device enumeration or context creation.

Common symptoms include:

[ERROR] clw-gpu-not-found: No OpenCL GPU devices available on platform.

CLW_ERROR: clwGetGpuDevice() returned CLW_NO_GPU_FOUND (code: -1001)

Failed to create GPU context: clw-gpu-not-found. Falling back to CPU (performance degraded).


Programs relying on GPU acceleration, such as compute shaders, machine learning inference, or scientific simulations built with OpenClaw, will either crash, log the error and degrade to CPU mode, or exit with a non-zero code. On Linux systems, you might see this in `dmesg` or application logs alongside OpenCL ICD loader warnings. Windows Event Viewer may log ICD-related failures under "Application" events. Performance drops are noticeable: GPU-bound kernels run 10-100x slower on CPU fallback.

In verbose mode (e.g., `CLW_LOG_LEVEL=debug`), additional diagnostics appear:

[DEBUG] Platforms found: 1 (Intel CPU only) [DEBUG] GPU devices on platform 0: 0 [ERROR] clw-gpu-not-found
