jgrusewski 26ffa7ad72 fix: event-based cross-stream sync for best-model restore (no CPU stall) ...

Replace stream.synchronize() with cuStreamWaitEvent for cross-stream
visibility of restored weights. The trainer writes best params on its
stream, records a CudaEvent, and the evaluator waits on that event
on ITS stream via cuStreamWaitEvent — purely GPU-side dependency,
zero CPU blocking.

Previous fix (stream.synchronize) was a CPU stall that hid the issue.
This is the proper CUDA approach: inter-stream event dependencies.
