Subject: [PATCH] feat: add preStart hook for nixos-upgrade service

Introduce a preStart hook to the nixos-upgrade systemd service to ensure the local repository is updated before upgrades by fetching and resetting to the origin's HEAD. This enhances the reliability and consistency of the upgrade process. Also, maintain the commented out old flake path for backward traceability.
