Missing `.data` directory in version control

[PaulRBerg]

I've git cloned the repo, ran pnpm install, then pnpm dev, and I got this error:

NotFound: FileSystem.readFile (/Users/prb/pad/effect-nextjs-example/.data/todos.json): ENOENT: no such file or directory, open '/Users/prb/pad/effect-nextjs-example/.data/todos.json'

Consider not git-ignoring todos.json and providing some dummy data upon starting the app.
