v0.22.1: sync CLI, reaper TZ fix, maintenance-cron self-heal

- wp prautoblogger generate --sync: synchronous VPS orchestrator mode.
  Acquires lock in-process, calls on_orchestrate_tick() then loops
  on_generate_tick() up to 20 ticks. Emits JSON summary; exits 0/1.
- Generation_Checkpoint_Runner::set_sync_mode(): static flag suppresses
  wp-cron reschedule inside on_generate_tick() when the VPS external
  loop is the driver. No effect on existing async (cron/AJAX) paths.
- Run_Reaper TZ fix: sweep_stuck_stages() + sweep_stuck_runs() now use
  wp_date() for $cutoff so it matches updated_at's local-TZ storage.
  gmdate() was 8h behind on Hostinger (UTC+8) — latent for old stale
  runs but would suppress reaping of same-day-stalled runs.
- DB_Migrations v0221 self-heal: restores missing maintenance crons
  (reap_orphan_research_rows, collect_metrics, sync_runware_models).
  prautoblogger_daily_generation deliberately NOT re-registered — VPS
  systemd timer owns generation scheduling. Note: wp-cron reliability on
  this Hostinger host is suspect; maintenance crons are low-stakes.
