fix: VPS-orchestrated generation reliability — generate --sync, reaper TZ fix, maintenance-cron self-heal (v0.22.1) (#171)

Browse Source 
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).

QA: APPROVE @ 0689989 (qa-reviews/prautoblogger/2026-06-23-0689989.md). CEO greenlight 2026-06-22.
