 * without the CUDA runtime — ORT throws during session construction instead
 * of silently falling back to CPU. We catch that, log once, and retry with
 * whichever safe provider (`cpu` or `wasm`) was in the original list (or
 * default to `cpu` / `wasm` based on the ORT binding shape).
 *
 * Throws the original error if the provider list was already safe-only.
