Problem

The "Run in another region" step in "Try next" had two issues:

• fly regions add nrt no longer works. The CLI now fails with This command is no longer supported; use fly scale count ....
• Adding a region and refreshing the page doesn't show the new region, because Fly routes each request to the nearest machine.

Changes

• views/index.ejs: replace fly regions add nrt and fly scale count 2 with fly scale count 2 --region nrt.
• views/index.ejs: drop the "then refresh to see a different region" text. In its place is a copyable curl -H "fly-prefer-region: nrt" https://<app>.fly.dev command, with the app name filled in from the page, to target the new region explicitly.
• AGENTS.md: make the same change to the "Things to try" entry.

Testing

• Ran the server locally and confirmed the page renders with the new commands and copy buttons.
