Add getOGImageUrl() that appends a v=timestamp param (using & when the URL already has a query string). Use it for all /api/og metadata so social previews pick up regenerated OG images instead of stale cached responses. Co-authored-by: Ankesh Bharti <hey@ankeshbharti.com>

Summary
Social crawlers and CDNs often cache Open Graph image responses aggressively. The site serves dynamic previews from
/api/og, but metadata pointed at a stable URL, so updated images could appear stale.Changes

Each new deployment gets a new build time, so the
vvalue changes on deploy and encourages fresh fetches without manual cache purges.
