"vp create vite:<unknown>" crashes with ENOENT instead of showing a helpful error message

Describe the bug

When running vp create with an unknown vite: prefixed template name (e.g. vite:test, vite:other), the CLI crashes with an unhandled ENOENT error instead of showing a clear error message.

Expected:

A clear error message like Unknown builtin template "vite:other". Run vp create --list to see available templates.
