Add Prettier & ESLint Config to Generated Projects

[Josephat-S]

What to build

Generated projects should come with pre-configured Prettier and ESLint so users have code quality tools from day one. Add .prettierrc, update .eslintrc.json, and add format and lint:fix scripts.

Files to modify

• templates/*/nextjs-monolith/package.json (add prettier devDep, add scripts)
• templates/*/nextjs-monolith/.prettierrc (Create)
• templates/*/nextjs-monolith/.eslintrc.json (Modify — add prettier plugin)

Acceptance criteria

• Every generated Next.js project has a .prettierrc (single quotes, trailing commas).
• package.json includes prettier as a devDependency.
• npm run format script runs Prettier on the project.
• npm run lint:fix script runs ESLint with auto-fix.
• No conflicts between ESLint and Prettier rules.

Dependencies

• None
