Subject: [PATCH] Fix compat with extensionless scripts/* imports
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary:
**Context**

Replaces https://github.com/react/react-native/pull/57709, which identified a real bug in 0.87 from the combination of:

- https://github.com/react/react-native/pull/57276
- https://github.com/react/react-native/pull/57652

```
$ npx react-native spm add
error Cannot find module '.../node_modules/react-native/scripts/setup-apple-spm'

$ npx react-native codegen
error Cannot find module '.../node_modules/react-native/scripts/codegen/generate-artifacts-executor'
```

**This diff**

- Fix — and exclusively switch to — extensionless imports rather than requiring `.js`.
- Update in-repo consumers.

The previous single mapping is now an extension-aware mapping:
- `./scripts/*` now appends `.js`, so `react-native/scripts/foo` resolves to `foo.js`.
- `.sh` and `.rb` stay reachable via explicit `./scripts/*.sh` and `./scripts/*.rb` passthrough patterns.

**Impact**

- Explicit `react-native/scripts/*.js` specifiers no longer resolve, so JavaScript paths must be imported without an extension.
- Files under `scripts/` with extensions other than `.js`, `.sh`, or `.rb` are no longer exposed through `./scripts/*`.
    - These have no open source consumers.

Changelog:
[General][Fixed] - (RC4 only, drop for main changelog): `react-native/scripts/*` imports once again expand `.js` extensions
[General][Breaking] - Extensionless `react-native/scripts/*` imports are now **mandated**; explicit `.js` import specifiers are rejected.
