v0.2.12

Fix: generation stampede / site stuck under load

Root cause

Cache-clear hooks (WP Rocket / Autoptimize) were force-regenerating up to 50 pages synchronously. Each success flushed all caches, which retriggered those hooks — a feedback loop that hammered WordPress and the VPS.

Changes

• Do not regenerate critical CSS on cache purge (it lives in post meta)
• Purge only the affected URL after generate (no full-site flush)
• Background queue: one generation at a time with a site-wide lock
• Publish/cron enqueue instead of blocking the request
• Rate limit always applies (default 5/hour/page); default delay 5s

Update the plugin, then optionally enable Disable Regular Intervals until the queue drains, and purge any stuck WP-Cron backlog if needed.
