Hey maintainers! 👋 @c-ehrlich @juliusmarminge @nexxeln @t3dotgg

Excited to share this new addition to create-t3-app! This PR brings a much-requested feature from issue #2139 - giving users control over build error handling.

What's New

✨ Smart Build Error Management

• Users now get asked during setup: "Want to skip TypeScript and ESLint build errors?"
• Perfect for when you're prototyping or dealing with legacy code
• Your build process, your rules!

How It Works

🚀 Flexible & Optional

• Adds a simple yes/no question in the setup flow
• For CI lovers: --ignoreBuildErrors flag does the trick
• Only updates next.config.js if you say "yes" - no surprises!

When enabled, your Next.js config gets:

// Peaceful development mode activated! 🕊️
typescript: { ignoreBuildErrors: true },
eslint: { ignoreDuringBuilds: true }
