# gitPerformUpdate — the proven, file-level LibrePortal update.
#
# Backs up the user's configs/logs, re-clones the repo fresh (gitReset), then
# restores the configs/logs over the clean checkout, zips a snapshot, prunes
# old backups, and stops tracking ignored files. This is the historical update
# body that "worked great" — extracted out of gitFolderResetAndBackup so it can
# be reused non-interactively by the WebUI updater (webuiRunUpdate) WITHOUT the
# trailing `exit` the interactive CLI flow relies on.
#
# Does NOT exit, restart, or redeploy — the caller decides what happens next.
