An API you can curl, or open in a browser, to receive Bluesky data as markdown!
Tighten rate limit to 10/min, add 8s API timeout
- Rate limit: 20 → 10 req/min per IP for more headroom against abuse
- 8s AbortController timeout on all Bluesky fetch calls so a hung
upstream releases the function slot before Vercel's 10s hard kill
