Unable to catch exception in wgpuDeviceSetUncapturedErrorCallback

When calling dispatchKernel throws the runtime exception in wgpuDeviceSetUncapturedErrorCallback, try-catch around dispatchKernel does not catch the exception.
https://github.com/AnswerDotAI/gpu.cpp/blob/main/gpu.h#L791

A thread other than the main thread may be throwing the exception.

從 gpu.h#L791 開始，追蹤在呼叫 dispatchKernel 時 wgpuDeviceSetUncapturedErrorCallback 如何回報錯誤。使用圍繞 dispatchKernel 的 try-catch 重現該失敗，然後驗證預期的例外行為能夠跨越所回報的執行緒邊界正常運作。
