Add gpu_idx + gpu_name to submit telemetry

FinishedJob now carries the GPU ordinal and device name (from run_on_gpu),
and submit_job sends them as gpu_idx (number) and gpu_name (string)
alongside the download/run/cubin/version params. So the platform can see
exactly which GPU produced each fragment.

Prepares 0.1.21 (version bumped); release is held pending sign-off.
