Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

🦉 Regular Expression Denial of Service (ReDoS)

[snyk-io]

This upgrade contains major versions for both react-native and its CLI, introducing significant breaking changes and a critical version mismatch between the two packages.

1. react-native 0.75.4 → 0.84.0 (HIGH RISK)

This is a substantial upgrade across nine minor versions, introducing major architectural changes, new requirements, and deprecations. The risk is high due to the sheer volume of changes and the effort required to migrate.

Key Breaking Changes:

• Node.js Requirement: React Native 0.84.0 requires a minimum Node.js version of 22.
• Legacy Architecture Removed: Starting in 0.84.0, Legacy Architecture code is no longer included in iOS builds by default. Apps not already migrated to the New Architecture will be significantly impacted.
• API and Module Changes: Numerous APIs have been changed or removed between versions 0.75 and 0.84. For example, the JSIModule API was removed in 0.75, and Android's PopupMenu was extracted to a separate package.
• Precompiled iOS Binaries: Version 0.84.0 enables precompiled binaries for iOS by default, which changes the build process.

2. @react-native-community/cli 10.2.7 → 13.5.2 (HIGH RISK due to incompatibility)

While this CLI upgrade has its own breaking changes, the primary issue is its incompatibility with react-native@0.84.0.

• Version Incompatibility: According to the official compatibility matrix, @react-native-community/cli@13.x is intended for use with react-native@~0.74.x. Using it with react-native@0.84.0 is unsupported and will likely lead to build failures and runtime errors.
• CLI Breaking Changes: Version 12.x raised the minimum Node.js version to 18 and replaced command-line flags like --variant and --configuration with --mode.

Recommendation:

1. Correct CLI Version: Before proceeding, update @react-native-community/cli to a version compatible with react-native@0.84.0 (likely ^20.0.0 or newer).
2. Use Upgrade Helper: This upgrade should not be attempted manually. Use the official **
