RestoreHelper

Restore counterpart to BackupHelper. Pulls latest backup from USB stick onto C:. SIDs differ post-reinstall so ACLs are reset per profile (icacls /reset + grant user/Admins/SYSTEM). NTUSER.DAT and AppData\Local skipped — would corrupt fresh registry/cache state. Idempotent via "BackupRestored" log marker.
