Persist the cold-boot wins (was: only manually deployed via tmp/20260501_restart_timing/deploy-fast.sh, would silently revert on the next prod firmware update). - Install bbserial-rebind.service alongside bbctrl.service and enable it. Eliminates the rc.local bbserial reload mid-boot. - Prefer scripts/rc.local.fast over scripts/rc.local when present. Legacy rc.local left as a fallback for old firmware tarballs. - Mask plymouth-read-write, plymouth-quit-wait, and raspi-config. Together these were ~6s of userspace startup that bought nothing on a deployed Onefinity Pi. Cumulative: bbctrl listening at boot+10.6s (was 20.6s), userspace boot 11.5s (was ~13s), bbctrl.service @2.9s in critical-chain (was @6.5s after the first optimisation pass).
