Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/52528

+- **APIs:** All `react-native/Libraries/BugReporting` APIs have been removed ([9d4d8dcb02](https://github.com/facebook/react-native/commit/9d4d8dcb0264273cc1522ed6e9de47cdb05606f4) by [@huntie](https://github.com/huntie))
+- **APIs:** Add public JS API breaking change detection under `yarn diff-api-snapshot` script. ([6b40f35032](https://github.com/facebook/react-native/commit/6b40f35032462de8a9bad0e9f186916562475a40) by [@coado](https://github.com/coado))
+- **APIs:** Community CLI users: user-defined `resolver.resolveRequest` and `serializer.getModulesRunBeforeMainModule` Metro config now takes precedence over CLI defaults ([fe2bcbf4ba](https://github.com/facebook/react-native/commit/fe2bcbf4ba7ce983fac0cd09727c165517b6337f) by [@robhogan](https://github.com/robhogan))
+- **Error Handling:** Improve messaging and add error stack trace for uncaught throws. ([5ba0e1f97a](https://github.com/facebook/react-native/commit/5ba0e1f97ad40f84d83efaa9cfdbaf9ad22a18e8) by [@vzaidman](https://github.com/vzaidman))
+- **Flow:** The `react-native` package no longer ships with the `flow` directory ([38acb4c074](https://github.com/facebook/react-native/commit/38acb4c0746e48ebb10729360788e26454736d1b) by [@huntie](https://github.com/huntie))
+- **Node:** Minimum Node version is now bumped to Node.js 22.14.0 ([df39eadc03](https://github.com/facebook/react-native/commit/df39eadc03edcd23fab47712d24818d2d0c75d16) by [@huntie](https://github.com/huntie))
+- **View:** `View` no longer sets any default accessibility props, which should not result in visible changes in behaviour but may affect snapshot tests. ([039a333df5](https://github.com/facebook/react-native/commit/039a333df57e20133af3ec77e995ec8fe4dc7f5c) by [@javache](https://github.com/javache))

+- **Kotlin:** Migrate `ViewManagerInterfaces` to kotlin.

+- **SynchronouslyUpdateViewOnUIThread:** `SynchronouslyUpdateViewOnUIThread` now accepts `folly::dynamic` instead of `NSDictionary`. Use https://github.com/facebook/react-native/blob/main/packages/react-native/ReactCommon/react/utils/platform/ios/react/utils/FollyConvert.h#L14 for conversion.

+### Changed
+
+- **Animated:** Animated now always flattens `props.style`, which fixes an error that results from `props.style` objects in which `AnimatedNode` instances are shadowed (i.e. flattened to not exist in the resulting `props.style` object).
