Summary:
There are some duplicated function calls in `PerformanceEntryReporter::reportMark()` . I know this is a micro optimization but I feel this way the code is cleaner.
This is called through `performance.mark` so there is potentially a tiny little performance improvement here?

Summary:
`new_architecture.rb` script looks for `Info.plist` files in IOS directory, and adds RCTNewArchEnabled field to each one, except for those explicitly excluded. Framework files should remain unchanged, so I've extended the excluded_info_plist dict.
Modifying framework's Info.plist can break pod installation with errors like:
```
[!] An error occurred while processing the post-install hook of the Podfile.
invalid byte sequence in UTF-8
```

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).

The Modal view creation contains initial properties when using Props 2.0. This diff adds support for Modal view creations having initial properties by allowing the `updateProperties` fast path only if the dialog is already initialized.
Without the change, the fast path gets called before the dialog could be initialized which leads to throwing an exception when the dialog is being checked to see if it is initialized.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52692
D77341994 added a global cache for Facsimile layouts, where we will reuse an existing `android.text.Layout`, and `Spannable`, if one already existed for a same AttributedString, under same layout constraints. An error here, is that we consider a layout reusable, even when shadow views are different, which means there may be different react tags in the underlying AttributedString.
This leaks into the layout itself, and means that if a layout is reused, we can hit test against a stale/incorrect react tag.
The solution to allow reuse here, is to avoid embedding react tag directly into the `android.text.Layout` structure. Instead, we replace references to react tags, with a fragment index, and embed the list of fragment indices in each PreparedLayout. We can hide this "cleverness" within the boundary of `TextLayoutManager`, such that an invalid `PreparedLayout` is never allowed to escape.

Changelog: [ANDROID][FIXED] Update font scale when recreating `RootView`
At the moment `enableFontScaleChangesUpdatingLayout` flag only works when the activity is configured to handle font scale changes by itself (`configChanges="fontScale"` in the manifest).
When that configuration is missing, the OS handles the font scale changes by recreating the activity, but in this case the path responsible for updating internally kept font size isn't executed.
This diff updates the RootView, so that the display metrics are also updated when it's created. Alternative approach would be to do that on the Activity, but that assumes usage of `ReactActivity`.
