Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49198
changelog: [internal]
The work done on the main thread should scale with what is on the screen. React Native shouldn’t block the main thread for off screen elements that do not affect what is shown to the end user. When React schedules a commit, only views needed to achieve a screen full of content should be materialised and added to the host platform’s view hierarchy.
With Fabric View Culling, views that do not contribute pixels to the screen will not materialize and updates to them will be skipped. React Native will focus system resources on what is visible to the end user.
Fabric View Culling maximises benefits from view recycling. Each UI element such as text, image, or video is recycled individually. As soon as an item goes off screen, it can be reused anywhere in the UI and pieced together with other items to create new UI elements. Such recycling reduces the need of having multiple view types and improves memory usage and scroll performance.
In the example bellow, view B will not be mounted because the user can't see it.

The difference in number of allocated views:
Please note, the screenshots below are from Xcode View Hierarchy debugger. To show how many views are allocated in memory, I disabled [removeClippedSubviews](https://reactnative.dev/docs/scrollview#removeclippedsubviews) flag globally.

| {F1974949979}| {F1974949981}
# Disclaimer, this is not a complete implementation
This implementation is not complete and it is missing to handle edge cases.
Things that are missing:
- Transform style is not taken into account.
- removeClippedSubviews is not respected. Fabric View Culling happens unconditionally for every scroll view.
- Fabric View Culling does not respect when ScrollView has overflow set to visible.
- Fabric View Culling is only performant enough on iOS.
- [enableSynchronousStateUpdates](https://github.com/facebook/react-native/blob/main/packages/react-native/scripts/featureflags/ReactNativeFeatureFlags.config.js#L248) must be enabled for Fabric View Culling to work correctly.

Adds minimal dependency resolution to `yarn build-types`.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49241
In auditing differences between `InteractionManager` and `InteractionManagerStub` (used to evaluate to entirely remove the former all together), I noticed a behavioral disparity with how errors are handled.
In `InteractionManager`, the promise that's returned is never rejected, whereas `InteractionManagerStub` propagates errors by rejecting the promise that's returned. This changes `InteractionManagerStub` to behave like `InteractionManager` for the purpose of comparing apples-to-apples.

Summary:
Fantom was disabling Metro hierarchical lookup in all cases when `JS_DIR` is set. The intention is that `node_modules` folders other than the configured `JS_DIR/public/node_modules` are not used.
However, this leads to incorrect resolution where a transitive dependency is not hoisted. If the origin of the resolution is already inside `node_modules`, we must perform a hierarchical lookup to avoid picking up just whichever version happens to be hoisted to `node_modules` root.

Pull Request resolved: https://github.com/facebook/react-native/pull/49254
Changelog: [internal]
This is just a convenience method to do:
```
Fantom.dispatchNativeEvent(node, 'click');
```
Instead of:
```
runOnUIThread(() => {
enqueueNativeEvent(node, 'click');
});
runWorkLoop();
```
Which is too verbose and people rarely need this level of granularity in tests.
Note that, in Fabric, we have methods called `dispatchEvent` that don't match 1:1 with this API. In that case, `dispatchEvent` is more aligned with Fantom's `enqueueNativeEvent`.

Changelog: [internal]
Renaming this low level method as `enqueue` is more accurate in this case than `dispatch`, which is misleading because it actually doesn't dispatch it to JS.
We should also rename this in Fabric, but that's a larger and breaking change, so just making the change in Fantom for now. This is a trade-off between convenience/ergonomics of the testing API vs. alignment with the internal nomenclature. In this case we favor the first.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/49184
D65645985 shipped a refactor to `Animated`, so that it would use a custom `useAnimatedPropsMemo` instead of `useMemo`. This significantly improved update performance by no longer invalidating the `AnimatedProps` on effectively every update to `Animated` components.
However, this was measured to increase memory usage. After a few experiments, we identified that use of the in-band state update was responsible for the memory regression. While this requires further root cause investigation, this diff attempts to mitigate the memory regression.
This diff introduces a feature flag that enables an implementation that minimizes duplicated work, such as unnecessarily computing `compositeKey` or creating new instances of `AnimatedProps`. In addition, this implementation strives to do so without significantly degrading when an update is interrupted by a concurrent update.
