Detailed Description

GPU-accurate interval timer using a CUDA event pair.

Provides CudaTimer, a lightweight RAII wrapper around two cudaEvent_t handles (start and stop). The timer records events into a CUDA stream at the desired measurement points and reads the elapsed GPU time after the stream reaches the stop event.

Intended use:

• Beta.1 profiling pass: per-operation GPU timing in CudaProfileScope.
• Fine-grained kernel sequence measurement without host-side synchronization at every boundary.
