Extended ONNX Runtime CUDA sidecar repair to PI_TINY_DEVICE=auto and gpu on Linux x64, matching the CUDA-capable diagnostics path.
Added focused regression coverage for both generic accelerated settings.

Deferred ONNX Runtime CUDA sidecar repair failure into the runtime metadata so loadTransformersRuntime keeps loading and loadPipelineWithDeviceFallback still gets its CUDA→CPU retry when NuGet is offline or the ort install script is unavailable. The failure surfaces through the CUDA diagnostics helper instead of hard-erroring the tiny worker.

Downloaded missing ONNX Runtime CUDA provider sidecars when the compiled tiny-model side runtime is used with PI_TINY_DEVICE=cuda.
Preserved actionable CUDA worker diagnostics in tiny-models text output and added focused regression coverage.
