Keep the SWC builder (default in Nest 11) for ~20x faster builds

  "compilerOptions": {
    "builder": "swc",
    "typeCheck": true
  }
}

Nest 11 defaults to the Rust-based SWC compiler, which is dramatically faster than `tsc` for builds and dev restarts. SWC transpiles but does not type-check, so enable `typeCheck: true` to run type checking in parallel and keep your safety net. Only fall back to the `tsc` builder if a plugin you depend on relies on the TypeScript compiler API (some transformers do). For most apps, staying on SWC is the right call.
