TurboModule Spec Codegen Naming

A TurboModule spec compiles in TypeScript but Codegen silently skips it — spot why the native binding never generates.

Codetypescript

// NativeCalculator.ts
import type { TurboModule } from 'react-native';
import { TurboModuleRegistry } from 'react-native';

export interface Calculator extends TurboModule {
  add(a: number, b: number): number;
  getConstants(): { version: string };
}

export default TurboModuleRegistry.getEnforcing<Calculator>('Calculator');

This file type-checks fine, but Codegen never produces the native spec and the app crashes with 'module not found'. What is the bug?
