Summary:
Defines module for `React-jsinspector` that for swift modules to integrate with.
to fix https://github.com/expo/expo/issues/28209, any podspec depends on HermesExecutorFactory should use ` add_dependency(s, "React-jsinspector", :framework_name => 'jsinspector_modern')` to add dependency. otherwise it will encounter the header not found issue because use_frameworks will change "jsinspector-modern" to "jsinspector_modern".
to depend on React-jsinspector from expo-modules-core, we need it to define as a module.
otherwise, it will have the error
```
The Swift pod `ExpoModulesCore` depends upon `React-jsinspector`, which does not define modules. To opt into those targets generating module maps (which is necessary to import them from Swift when building as static libraries), you may set `use_modular_headers!` globally in your Podfile, or specify `:modular_headers => true` for particular dependencies.
```

Summary:
Web props work (somewhere around D41230978 and D39268920) made it so that numeric font weights can be set instead of just strings. This is implemented by converting number to string before passing to native component within the `Text` component.
We have crash with:
```
2024-04-19 09:38:21.360 16963 17190 E ViewManager: Error while updating prop fontWeight
2024-04-19 09:38:21.360 16963 17190 E ViewManager: java.lang.IllegalArgumentException: method com.facebook.react.views.text.ReactBaseTextShadowNode.setFontWeight argument 1 has type java.lang.String, got java.lang.Double
2024-04-19 09:38:21.360 16963 17190 E ViewManager: at java.lang.reflect.Method.invoke(Native Method)
```
`TextStyleProps` can also be passed to `TextInput`, which passes to underlying native component, without going through this logic. And the types for Native props directly derive from JS props, so type system does not catch passing incorrect number type to underlying native component.
This does a quick and dirty replication of the exact logic in `Text.js` to `TextInput.js`. I'd love to potentially fix this up for Fabric in a different way when we rethink CSS parsing.

## Changelog:
[Android] [Fixed] - fix a case when view preallocation or props forwarding on Android lead to dropped props update
# What does this fix
This fixes a bug where prop change is not delivered to Android mounting layer if the prop change was initiated from state update inside of `useLayoutEffect`, `componentDidMount` or `componentDidUpdate`.
This affects android only and when batched rendering is enabled.
There are two root causes of this problem:
1. View preallocation on Android: https://fburl.com/code/r62p3vot
2. Prop forwarding on Android: https://fburl.com/code/644f1ppk
Minimal repro :
```
import React, {useLayoutEffect, useState} from 'react';
import {Button, SafeAreaView, View} from 'react-native';
function Foo() {
const [bgColor, setBgColor] = React.useState('red');
useLayoutEffect(() => {
console.log('useLayoutEffect');
setBgColor('blue');
}, []);
return (
<View
style={{
backgroundColor: bgColor,
width: '100%',
height: '100%',
}}
/>
);
}
function RNTesterApp() {
const [show, setShow] = useState(false);
return (
<SafeAreaView>
<Button title="Toggle" onPress={() => setShow(!show)} />
{show && <Foo />}
</SafeAreaView>
);
}
export default RNTesterApp;
```
# The underlaying problem
The problem is combination of view preallocation and batched rendering updates.
Here is a step by step what happens in the repro above:
1. React issues asks Fabric to create new shadow node A with background colour **red**.
2. Fabric asks Android to allocate a view for shadow node A with background colour **red**.
3. React commits tree **T1** and calls layout effects. Meanwhile Fabric waits, without trying to mount the tree **T1**, to prevent painting state that is about to be updated and prevent flickering.
4. React clones node A, changing the background colour to **blue** and commits the new tree **T2**.
5. Fabric, will now go ahead and mount the latest tree **T2**. While creating mount instructions, it will drop prop updates because it believes prop updates where delivered already as part of step 2.
# The fix
The fix is to change two things:
1. Ignore view preallocation for shadow nodes which were cloned with new props.
2. Set hasBeenMounted flag on ShadowNode later in the Fabric pipeline to fix it.
Both of these are hidden behind a single feature flag: `fixMountedFlagAndFixPreallocationClone`
## Performance implication:
I estimate that this will impact around 3% of views.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/44188
The current approach used for `batchRenderingUpdatesInEventLoop` is not compatible with Android due to limitations in its props processing model. The raw props changeset is passed through to Android, and must be available for the Android mounting layer to correctly apply changes.
We have some logic to merge these payloads when multiple ShadowNode clones take place but were previously assuming that a ShadowTree commit was a safe state to synchronize.
In the current implementation this means that two commits driven from layout effects (triggering states A → B → C) may cause Android to observe only the B → C props change, and miss out on any props changed in A → B.

## Changelog:
[Android] [Fixed] - When React Native is destroyed, unmount all Fabric surfaces.
Previously, Fabric surfaces would not be torn down. Meaning that passive and layout effects wouldn't be unmounted and surface infra wouldn't be cleaned up.
For example:
```
useEffect(() => {
return () => {
console.log('unmounted');
}
)};
```
When calling `ReactNativeHost.clear()` on Android in native code, the above effect should be unmounted.
This is a requirement for Fabric.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/42115
React Native Android had a concept called JSIModules, which iOS doesn't have. The JSIModule concept was introduced in the early stages of the Fabric project to represent modules that interact with JS through JSI and they are not NativeModules.
In the new architecture this concept is not really necessary and these interfaces were only used to initialize and destroy the Fabric renderer and TurboModule Manager in react native core. Bridgeless mode doesn’t use JSIModule anymore. Also, it has an explicit list of supported JSI module types, so is not open for extension.
In order to simplify RN concepts and reduce confusion with TurboModules, which also "use JSI", deleting everything related to JSIModule. This was already deprecated in 0.74.0.
Please use ReactInstanceEventListener to subscribe for react instance events instead of getJSIModule() and we recommend using TurboModules instead of JSIModules.

## Changelog:
[General][Changed] Disable new event loop behavior when bridgeless (new architecture) is enabled.
# What is the problem
With event loop, specifically with `batchRenderingUpdatesInEventLoop`, prop change is not delivered to Android mounting layer if the prop change was initiated from state update inside of `useLayoutEffect`, `componentDidMount` or `componentDidUpdate`. Note this has to be a prop change affecting mounting layer directly, not something consumed by Yoga, e.g. background colour or border colour.
This affects android only.
Minimal repro :
```
import React, {useLayoutEffect, useState} from 'react';
import {Button, SafeAreaView, View} from 'react-native';
function Foo() {
const [bgColor, setBgColor] = React.useState('red');
useLayoutEffect(() => {
console.log('useLayoutEffect');
setBgColor('blue');
}, []);
return (
<View
style={{
backgroundColor: bgColor,
width: '100%',
height: '100%',
}}
/>
);
}
function RNTesterApp() {
const [show, setShow] = useState(false);
return (
<SafeAreaView>
<Button title="Toggle" onPress={() => setShow(!show)} />
{show && <Foo />}
</SafeAreaView>
);
}
export default RNTesterApp;
```
# The underlaying problem
The problem is in batched rendering updates and how props are delivered to Android mounting layer.
Here is a step by step what happens in the repro above:
1. React issues asks Fabric to create new shadow node A with background colour **red**.
2. Fabric asks Android to allocate a view for shadow node A with background colour **red**.
3. React commits tree **T1** and calls layout effects. Meanwhile Fabric waits, without trying to mount the tree **T1**, to prevent painting state that is about to be updated and prevent flickering.
4. React clones node A, changing the background colour to **blue** and commits the new tree **T2**.
5. Fabric, will now go ahead and mount the latest tree **T2**. While creating mount instructions, it will drop prop updates because it believes prop updates where delivered already as part of step 2.
At first this might appear as a problem with view preallocation. But the underlaying trouble is that on Android, we currently have no way of knowing how to combine changesets from React into single folly::dynamic.
