Summary:
We need to upgrade the targetSdk to 36, which requires ensuring compatibility with the latest Android APIs and addressing any deprecations or behavior changes introduced in this version.
## Changelog:
[Android] [Changed] - Updated targetSdk to 36 in Android.
Pull Request resolved: https://github.com/facebook/react-native/pull/52355
Test Plan:
- Verified that the app builds and runs successfully with targetSdkVersion 36.
- Ran the full suite of unit and instrumentation tests: all tests passed.
- Manually tested key user flows (login, navigation, data sync) on devices running Android 14 (API 34) and emulator with API 36
- Confirmed that there are no runtime crashes or warnings related to `targetSDK` upgrade.

Adds support for the [`Network.getResponseBody`](https://chromedevtools.github.io/devtools-protocol/tot/Network/#method-getResponseBody) CDP event in `jsinspector-modern` and configures this for iOS. This enables us to populate the "Preview" and "Response" tabs in the React Native DevTools Network panel.
This is integrated with `RCTNetworking.mm` to support synchronously received `text` or `blob` data types, with incremental response support added next in D77457109.
**Implementation notes**
- Adds a new `BoundedRequestBuffer` construct to safely buffer response previews at a max memory size.
- `RCTNetworking` will always call `maybeStoreResponseBody` (when feature flag enabled), but is unaware whether there is an active CDP debugging session with network support or not.

Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52380
Apps that rely support focus in FlatList rendered items are missing out on a FlatList optimization that defers rendering for offscreen content updates.
For example, on Android, if you focus and smooth scroll an item into view, the onScroll event will fire first. For most sufficiently large virtualization windows, the next render will be delayed by the render batch timeout as most materialization of virtualized views is not treated as a high pri render.
However, this batch / timeout mechanism isn't being used for cell render updates that occur as a result of a focus change.
This change adds the same timeout mechanism used for scroll events. In most cases, the view that is focused is in the viewport, and the extra rendering needed is already scheduled (or executed with high priority if needed) when the onScroll event is processed.
In cases where the focus change occurs outside the viewport, most platforms will want to do some kind of "bring into view" anyway, and the same applies - onScroll will take care of scheduling the cell rendering priority.

Summary:
This change fixes an issue on iOS where gradients that fade to a transparent color-stop appear dark or "muddy." The fix ensures that the color's hue is preserved during the transition, matching the behavior on Android and web.
### The Problem
When creating a gradient on iOS (e.g., linear-gradient(red, transparent)), the transparent keyword is treated as transparent black (rgba(0,0,0,0)). The `CAGradientLayer` on iOS then interpolates all color channels linearly, causing the red, green, and blue components of the start color to fade to 0. This transition through black results in an undesirable dark or "muddy" appearance in the middle of the gradient.

[IOS][FIXED] - Gradient interpolation for transparent colors

This replaces `buildSpannableFromFragmentsOptimized()` with a more optimized version. There are a couple main changes.
1. We don't need a complicated structure around ordering, and span priority, that made its way from the Java ShadowNode logic. AttributedString already ensures there are no overlapping attributes per fragment.
2. `SpannableStringBuilder` is a complicated text-editor style data structure, optimized to allow text content to be modified, and spans re-applied. We can use a much lighter `SpannableString`, on top of the ahead-of-time known text content, which is faster, and saves around 500 bytes per string (and prepared layout). If we assign this to an `EditText`, which later gets edited, Android will copy it to a `SpannableStringBuilder`.

Adds a hyper-minimal build script using `electron/packager` that produces custom binaries for the experimental React Native DevTools standalone shell. The main user-facing benefit of this is replacing the Electron name and icon with our own branding.
NOTE: `electron/packager` is designed to include the application code in the resulting binary. This is arguably overkill for us - the current launch model of `electron src/electron/index.js` is actually wholly sufficient for what we need - but I decided to go with the grain of the available tooling for simplicity.

Fixes https://github.com/facebook/yoga/issues/1819
Yoga has a fast path when measuring a node, if it thinks it knows its dimensions ahead of time.
This path has some eroneous logic, to set both axis to owner size, if *either* will evaluate to zero, while having an `YGMeasureModeAtMost`/`FitContent` constraint. This means that if a node is given a zero width, and Yoga later measures with with `FitContent`, its height will become the maximum allowable height, even if it shouldn't be that large.
We can fix this, by only allowing if both axis are this fixed case, instead of just one.
This bug has existed for about a decade (going back to at least D3312496).

Summary:
There is an issue with keyboard navigation if some scroll view sets `snapToAlignment`. In this case, we are unable to find potential focus candidates if clipping is enabled since this prop will make it so that certain views in the hierarchy under the scroll view form a native view without any traits being set. The fix we have in place currently relies on `FormsStackingContext` to be set to discover potential candidates so it will break in this case. To fix this, we just return the entire ancestor list, since native will know how to deal with the cases that are not actual views, and in general has the official knowledge of what can be in the hierarchy or not.

Pull Request resolved: https://github.com/facebook/react-native/pull/52308
Experimentation shows, that we very heavily rely on the global text cache for performance (not sure how much of this is invalidation, vs repeated text, or revisiting previous surfaces).
This adds a global LRU cache, of prepared layouts, given a specific AttributedString and constraints. This is similar to the existing cache, with the caveat, that we need to have separate entries for any display states, instead of just those that effect metrics.
I sized it at 200 elements for now, since an Android `Layout` is much heavier than a `Size` (in practice, each seem to weight 1-3KB (though this will be significantly reduced with future change to move from `SpannableStringBuilder` to `SpannableString` and also contributes to the global JNI ref table, but set this up to be customizable via flag, so we can experiment, on perf impact, vs memory.
