This change reverts D78158734 which was a patch to make the dynamic frameworks work properly because we were not exporting the FBReactNativeSpec headers in prebuilds correctly.
This change fixes this, by exposritng those headers correctly.

Summary:
Hello, I work on [Radon IDE](ide.swmansion.com) I encountered an issue while adding support for react native 81, this PR solves it:
In https://github.com/facebook/react-native/issues/51023 EvanBacon removed `displayName` filed from `View` component adding the following comment:
>Remove displayName in favor of component name. I'm not 100% sure this is a full fallback but it is valid according to react/display-name eslint rule—https://github.com/jsx-eslint/eslint-plugin-react/blob/master/docs/rules/display-name.md
Unfortunately the Fabric renderer uses the `displayName` property to generate the name of the component for the inspector functionality and in absence of it generates a name that might be confusing to the end user:

Problem is not specific to Radon and happens in chrome devtools as well:

This PR brings back the `displayName` property to fix that.
[INTERNAL] [FIXED] - Bring back the displayName property to the View component
Pull Request resolved: https://github.com/facebook/react-native/pull/52688
Test Plan:
- Run the application
- open chrome devtools and navigate to "components" tab
- before changes the View components would show up as `View_withRef` after they are named `View`

The documentation for those methods mention that users should override them to
provide their own implementation.
However those vals are not `open` so users cannot really override them.
This fixes it.
See more context on https://github.com/facebook/react-native/pull/48800#issuecomment-3082665024
So this was practically a breaking change, that I'm attempting to mitigate.

Summary:
I've noticed that test_js (20) and test_js (24) are actually running on Node 22.
That's because the `yarn-install` action is invoking setup-node again with the default value (22).
This changes it. Also I'm cleaning up the workflows so that every `yarn-install` invocation is happening just after the `setup-node` invocation.

* Fix incorrect locking and attempts check in ShadowTree experiment (#52681)
Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52681
Changelog: [internal]
In the original change I made in D78418504 / https://github.com/facebook/react-native/pull/52645 I made 2 mistakes:
1. Used a lock that would try to re-lock on itself without it being recursive (which would cause a deadlock). I didn't see that because when testing I didn't hit the case where we'd exhaust the options.
2. The `attemps` variable wasn't incremented, so we never left the loop in case of exhaustion.
This propagates a flag to `tryCommit` to indicate we've already locked on the commitMutex_ so we don't need to lock again in that case and increases the counter, fixing the issue.

Changes `react-native/babel-preset` so that by default, `hermes-parser` is configured with `reactRuntimeTarget: "19"`. This changes the compiled output of Component Syntax to not use `forwardRef` when a `ref` prop is present.
Additionally, this adds a new preset option property, `hermesParserOptions`. This object allows users of `react-native/babel-preset` to supply overrides for any `hermes-parser` options.
Changelog:
[General][Changed] - Configures `react-native/babel-preset` to target React 19 by default, meaning Component Syntax will not compile to `forwardRef` calls when a `ref` prop is present.
[General][Added] - Added support to `react-native/babel-preset` for a `hermesParserOptions` option, that expects an object that enables overriding `hermes-parser` options.

This PR fixes two issues with `display: contents` implementation:
1. When a node with `display: contents` set is a leaf, it won't be cloned after the initial tree is built. The added test case covers this scenario.
2. It was possible for the subtree of `display: contents` nodes not to be cloned during layout. I don't have a minimal reproduction for this one, unfortunately. It was discovered in the Expensify app: https://github.com/Expensify/App/issues/65268, along with a consistent reproduction. In that specific case, it seems to be heavily tied to `react-native-onyx`, which is a state management library.

Summary:
When using prebuilts the USE_FRAMEWORKS setting is not really relevant for the React Native code, since there will not be any source code to build frameworks for - and because we already have a framework for the code in React.XCFramework.
This commit adds a new command to the React Native podspecs like we did with the ReactNativeDependencies framework. The method is called `add_rncore_dependency` and it does nothing when building from source - but when linking with the React.XCFramework it explicitly adds linking with the framework.
In addition there are a few places in the ruby code where we check for the USE_FRAMEWORK value and changes some settings - where needed this commit will add a separate check to ensure we're building from source when making these changes.
