Seed live AI source snapshots under home

Prepopulate /home/clawdie/ai with source snapshots for clawdie-iso, clawdie-ai, and colibri when available on the build host. Use git archive of HEAD so provider keys, .env files, tmp, caches, and uncommitted private state are not baked into the image.\n\nChecks: sh -n build.sh live/operator-session/clawdie-xfce-visuals-guard.sh live/operator-session/hw-report; ./scripts/check-format.sh; git diff --check.
