Turbopack skips gitignored directories during module resolution in
next build. Since src/generated/prisma was in .gitignore, the build
on CI failed with "Module not found: Can't resolve '@/generated/prisma'"
even though prisma generate created the files.
Fix: commit the generated client and remove it from .gitignore.
Run `npx prisma generate` after schema changes to update.
