Extracts Q/A pairs from the post body (an <h3> ending in the Persian
question mark ؟ followed by the next <p>) and emits FAQPage JSON-LD in
<head>. Makes posts with FAQ sections eligible for FAQ rich results in
Google. Non-question <h3> headings are ignored.

Verified: post with 3 h3s emits exactly 2 Question entries (the plain
heading excluded), valid escaped JSON.
