seo: optimize CTR for /blog/connect-ai-agents-behind-nat-without-vpn

Page: /blog/connect-ai-agents-behind-nat-without-vpn

Before (GSC): 492 impressions, 0 clicks, position 11.2 — ranking but not earning clicks.

Changes (CTR harvest, snippet-and-structure only — no substance rewrite):

• Rewrote title: Connect AI Agents Behind NAT - Without a VPN → How to Connect AI Agents Behind NAT Without a VPN (front-loads the query, states the deliverable).
• Rewrote meta description to directly restate the searcher's problem and promise the fix (STUN, hole-punching, relay fallback), within 155 chars.
• Tightened the opening paragraph to answer the query directly in the first two sentences (removed an unverifiable '88%'/StackOverflow claim not sourced anywhere).
• Added a 5-item FAQ block (feeds the FAQPage JSON-LD / AI Overviews via BlogLayout's existing faqItems prop).
• Added one contextual internal link to the companion post (openclaw-agents-behind-nat-zero-config) in the IoT Device Fleets section.
• URL/slug unchanged; all existing factual claims and code samples kept intact.

Verified: npm run build and npm run check:plain both pass.
