Stripe Projects concrete example design

Goal

Make the existing post demonstrate the exact benefit of Stripe Projects without turning it into a tutorial.

Approved change

Replace the generic Projects command list in “What it changes” with a compact api.example.com scenario:

• The user asks an agent to deploy a Worker on the free tier.
• Projects initializes the project, links Cloudflare through one human OAuth approval, provisions Workers access, and writes credentials to .env.
• The agent adds a Wrangler Custom Domain and runs wrangler deploy.
• Cloudflare creates the hostname's DNS record and certificate automatically.
• One sentence distinguishes this from arbitrary DNS management, which Projects does not currently expose.

Keep the addition to roughly 120–150 words and trim surrounding repetition so the full post remains concise.
