perf(infra): shallow (--depth 1) clone in golden-image provision

Browse source 
The forge will hold full main history (8.4G of old committed target/ blobs);
the build only needs the current tree (~209MB), so clone --depth 1 keeps cold
builds fast regardless of the bloat. Matches the existing shallow fetch path.
