Add sandbox testing and improve TTY error handling

- Add sandbox/ directory for testing (gitignored)
- Fix TTY initialization errors in Nuxt creation
- Add error handling to continue when app is created successfully
- Successfully tested Nuxt + Nuxt UI app generation

Testing shows Genesis creates working apps despite Nuxt CLI TTY issues.
