Subject: fix(build): keep private files out of the ISO, ship machine profiles

rsync -a copies by disk presence, so untracked personal-tooling state in the archsetup checkout rode into a portable USB image. The archsetup copy now excludes it.

The gitignored machine profiles (installer/*.conf) now ship to /root/ on the live ISO, so an unattended bare-metal reinstall has its profile without a repo checkout. The copy lists what shipped and warns when no profile exists. It also warns when a profile carries a non-placeholder credential, since the ISO is an unencrypted portable image.
