chore: vercel one-click deploy

[hi-ogawa]

Well, it looks like vercel understandably mis-detects framework as Next.js, so we might need to force framework: null.

Warning: Could not identify Next.js version, ensure it is defined as a project dependency.
Error: No Next.js version could be detected in your project. Make sure `"next"` is installed in "dependencies" or "devDependencies"

Not being able to do zero-config is unfortunate, but this should work now.
