Preserve the miner key across restarts.

If MINER_SSH is explicit and MINER_KEY is unset, the miner stage uses $RD/vast-m5/id_ed25519. On a later invocation, stage miner can skip that stage, but minerstart selects $RUN/id_ed25519 for the saved host. SSH then fails when the host accepts only the Vast key. Save the selected key with the miner address, or use the same fallback in both stages.

Review comment at @scripts/launch_cuda_run.sh at line 319:
Update the MINER_KEY selection and minerstart flow so an explicitly configured
MINER_SSH reuses the same selected key after a miner-stage restart or skip.
Persist that key with the saved miner address, or make minerstart apply the same
fallback as the miner stage.
