This adds a Gradle property called `exclusiveEnterpriseRepository`
that users can set in their `android/gradle.properties` as such:
```diff
# Use this property to enable or disable the Hermes JS engine.
# If set to false, you will be using JSC instead.
hermesEnabled=true
+exclusiveEnterpriseRepository=https://my.internal.proxy.net/
```
This will remove all the existing Maven repositories and only use the internal mirror they have.

[Android] [Added] - RNGP - Add support for `exclusiveEnterpriseRepository` to specify an internal Maven mirror.

Summary:
This React Native Android fix hardens the Fabric `InteropUiBlockListener` against `ConcurrentModificationException` crashes in `willMountItems` and `didMountItems`. By iterating over a shallow copy of the UI‐block lists and catching any mid‐iteration mutations, we ensure the listener never throws during a UI frame and always clears its pending blocks.
The issue was first reported in [React Native Issue https://github.com/facebook/react-native/issues/49783](https://github.com/facebook/react-native/issues/49783), and although [React Native PR#50091](https://github.com/facebook/react-native/pull/50091) was closed and not merged, the work in that PR did make it to React Native in [commit 17da3cb](https://github.com/facebook/react-native/commit/17da3cbbf4687f86226c4a80297c4d8abfc9c4f5). However, the fix didn't go far enough. We saw intermittent examples of this exception being thrown when swiping through a carousel from `react-native-reanimated-carousel`. This fix goes right to the exception site itself.

Test Plan:
The only way to test this is to develop a standalone app that emulates what we've been seeing in our commercially available RN app. We have done extensive testing of before (intermittent crashes) and after the fix (no crashes) and things have been standing up very well for us.
Here is a the Red Box we see right at the time of the crash, before this fix:

Summary:
FIXED Add index.js.flow to npm package files for Flow support
Currently, the distributed npm package for react-native does not include the index.js.flow file, which causes all exports to be typed as any when using Flow. This commit adds index.js.flow to the "files" array in package.json, ensuring Flow users receive proper type definitions out of the box. This addresses issues where type checking with Flow fails in React Native projects.

Summary:
After testing the latest RC and nighly builds, crash appeared when emitting events from turbo modules on 32bit Android devices. The crash is always reproducible only on 32bit devices on signed production builds. Fore more details and the crash log, check the [related issue](https://github.com/facebook/react-native/issues/51628#issue-3094045077).
From what I found, the variadic functions like CallVoidMethod are unsafe on 32bit due to not type checking the passed arguments at compile time. As far as I understand the 64bit cpus and ABIs are more forgiving with alignment and calling conventions. On 32bit the ABIs are strict as arguments are passed on the stack and if there is type/size/alignment issue it reads the wrong memory, which causes the SIGEGV crashes.
## Changelog:
[ANDROID] [FIXED] - emitting event from turbo module crashes on 32bit android
Pull Request resolved: https://github.com/facebook/react-native/pull/51695
Test Plan:
1. Pull the [reproduction demo](https://github.com/vladimirivanoviliev/rn079eventcrash), install the dependencies (v `0.80` is on PR)
2. Run codegen on android
3. Build signed apk. To create it you will need to create new demo key-store.
4. To install the build apk in 32bit mode you can use `adb -s YOURDEVICE install --abi armeabi-v7a android/app/release/app-release.apk`
5. Run the app, create key, save it. Than update the key and save it again. The app crashes when try to emit event from the turbo module.
6. Patch the related `JavaTurboModule.cpp` file with the changes from this PR and enable build from source.
7. Rebuild and reinstall the apk and test again - the issue is now fixed
## Additional notes:
I have tested the app on android using the `rn-tester` demo app, everything works as expected. I also patched our production app and tested more complex scenarios and they works as expected. I have run the tests and linter and they passed.
One thing that I didn't able to setup and run is the iOS `rn-tester` app, due to Hermes engine error `Command PhaseScriptExecution failed with a nonzero exit code`. I haven't found any information how to fix it. I have followed [this guide](https://github.com/facebook/react-native/blob/main/packages/rn-tester/README.md) and installed node modules using yarn and started the `yarn prepare-ios`. I also haven't found any information with what node version and ruby version the react native package is build on CI so I use the same versions locally. If you provide me with updated instructions for those I can contribute by updating the related guides and including `.npmrc`, `.ruby-version` files.

Re-expose **all `"./src/*"` paths via `package.json#exports`.
Follows D72228547 — as we'd attempted to be proactive with hiding `src/`, but are now reverting — essentially reducing this change as much as possible (read: most defensive/safer effect on OSS).
**Motivation**
Mitigates a warning emitted by Metro that may surface in new bare React Native template projects.
{F1978757796}
This is due to a 1P reference to `'react-native/src/private/featureflags/ReactNativeFeatureFlags` in `react-native/virtualized-lists`.
This is enough motivation to undo part of our change with introducing `"exports"` on `react-native` in 0.80.
**Especially**, to avoid confusion with other warnings we've intentionally introduced in 0.80 around subpath imports.
- The key difference is the above screenshot is from Metro and covers **any** import from any `node_modules` file — as opposed to just the immediate project.
Changelog:
[General][Changed] - Re-expose `src/*` subpaths when not using the Strict TypeScript API
The net breaking change for 0.80, once picked, is simply the presence of `"exports"` (only very edge case effects on expanding per-platform extensions, which we've mitigated). **All exported paths equivalent**.

Summary:
Calls to create timers should return sequential ids (integers greater than zero in the spec's words). This regressed in the `TimerManager` implementation, which instead starts at zero inclusively.
This has two side-effects for code assuming a spec-compliant implementation of `setTimeout` and `setInterval`:
- Calls to `clearTimeout(0)` or `clearInterval(0)` will potentially cancel scheduled timers, although it's supposed to be a noop
- Predicates like `if (timeoutId)` will fail since they assume non-negative ids
The change in this PR is to align with WHATWG HTML 8.6.2 (Timers): https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#timers
> otherwise, let id be an [implementation-defined](https://infra.spec.whatwg.org/#implementation-defined) integer that is **greater than zero** and does not already [exist](https://infra.spec.whatwg.org/#map-exists) in global's [map of setTimeout and setInterval IDs](https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#map-of-settimeout-and-setinterval-ids).
Specifically,
- we should return `0` to indicate that no timer was scheduled
- we should start generating timer IDs at `1` instead of `0`
This was previously raised in review comments here: https://github.com/facebook/react-native/pull/45092/files#r1650790008
The spec-incompliant behaviour was raised in an issue here: https://github.com/apollographql/apollo-client/issues/12632#issue-3075269978
This PR does not,
- add bounds checking on `timerIndex_` and add a search of an available id that isn't in the unordered map
- exclude `0` from being an accepted `TimerHandle` in `TimerManager::createTimer` or `TimerManager::deleteTimer` since the above bounds checking hasn't been added either
## Changelog:
[GENERAL] [FIXED] - Align timer IDs and timer function argument error handling with web standards.
Pull Request resolved: https://github.com/facebook/react-native/pull/51500

- Run `setTimeout` / `setInterval`; before applied changes the timeout for the first timer will be `0`
- Run `setTimeout(null)`; before applied changes the timer ID will be non-zero
- Run `setInterval(null)`; before applied changes an error will be thrown rather than `0` being returned

Expo is using the backingmap to be able to update properties in a fast and performant way in two overridden view manager subclasses (ViewGroupManager subclass is one of them).
This diff exposes the backing field via JvmName using the `internal_` prefix.
So Expo can keep on accessing the field as they were doing before. In the long run we should prevent them from accessing this property altogether but this would require a different API.
