Personalize section headers in template examples

Replace generic "Define/Build/Use the template" headers with
context-specific titles that describe what each section does:
- Docker: Install Docker, Build and publish, Run containers
- Next.js: Set up Next.js with shadcn, Build and publish, Access your app
- Expo: Create the Expo project, Build and publish, Access the dev server
- Desktop: Set up the desktop environment, Build and publish, Connect to the desktop
- Claude Code: Install Claude Code, Build and publish, Run AI prompts
