Commit 5c85987 appended a second copy of the toolkit-install/DNS-fix/
GPU-verify steps instead of inserting the new prerequisite-checks
section once. Removed the duplicate, keeping the more informative
GPU-check failure message from the second copy.
Checks Docker installed + daemon running, NVIDIA driver (nvidia-smi),
and curl. Prints specific install commands for each missing dependency
and exits early with a clear summary rather than failing partway through.
