Synchronous --sync CLI tick loop for VPS-driven generation over a held-open SSH session (survives Hostinger's ~10-min background-kill); $sync_mode guard on both tick handlers prevents double-drive; Run_Reaper UTC-vs-site-tz fix; one-shot self-heal migration restoring the maintenance crons that vanished after the 06-15/16 deploy (daily-generation excluded — VPS owns it).
