Summary:

NOTE: Resubmission of D110890810.

Replace 'react-native/Libraries/Core/InitializeCore' with an explicit 'react-native/setup-env' secondary export.

This was previously a special-case path excluded from our ESLint warnings. It is now formalised.

Changes

  • Add new src/setup-env.js entry point and package.json mapping.
  • Replace references in packages/metro-config/ and packages/community-cli-plugin/.
  • Update warn-on-deep-imports ESLint rule.

Changelog:
[General][Added] - Add 'react-native/setup-env' entry point. This replaces the previous side-effectful 'react-native/Libraries/Core/InitializeCore'.
[General][Deprecated] - Deprecate 'react-native/Libraries/Core/InitializeCore'. Use 'react-native/setup-env' instead.
