peptiderepo b5bbc54f87 fix: move Generate Now to background processing to avoid 120s timeout ...

Hostinger's LiteSpeed web server kills any HTTP connection that runs
longer than 120 seconds with a 500 "Request Timeout" error. The full
pipeline (Reddit fetch → topic scoring → article generation → editorial
pass → image gen ×2) takes 120-180s, causing "Request failed: error"
on every manual generation attempt.

Architecture change:
- Generate Now AJAX handler now schedules a one-shot WP-Cron event
  and returns immediately (~100ms response time)
- New prautoblogger_manual_generation cron action runs the pipeline
  in a separate PHP process free from the connection timeout
- Pipeline progress is written to a transient at each stage
- New prautoblogger_generation_status AJAX endpoint lets the frontend
  poll progress every 5 seconds
- Frontend auto-resumes polling on page load if a generation is running
- Direct wp-cron.php loopback ensures cron fires even if DISABLE_WP_CRON
  is set (common on Hostinger)

Version bump: 0.2.9 → 0.3.0
