feat: enable release profiling

[hurali97]

Description:

This introduces the core logic for react-native-release-inspector and cli. The usage is as simple as:

Install package:

yarn add react-native-release-inspector

Add import statement to the top of index.js

import '@callstack/react-native-release-inspector';
import { AppRegistry } from 'react-native';

Configure metro

const {
  withReactNativeReleaseInspector,
} = require('@callstack/react-native-release-inspector/metro');

...

module.exports = withReactNativeReleaseInspector(config, true);

Start the inspector

yarn inspector start

That is pretty much it. Build and run the application in release mode. The app should auto connect to the profiler.

Pull request overview

Introduces the initial implementation of react-native-release-inspector (runtime hook + Metro integration) and a new CLI that launches matching React DevTools, enabling profiling/inspection when running React Native apps in Release mode.

Changes:

• Add a new workspace package @callstack/react-native-release-inspector-cli and wire it into root lint/typecheck scripts.
• Implement @callstack/react-native-release-inspector runtime side-effect entrypoint plus a Metro config wrapper to inject it early and rewrite Fabric prod implementation to profiling.
• Update the example app to import the inspector, adjust Metro config, and run iOS Release by default; remove unused native TurboModule scaffolding.
