Summary of Changes

Hello @jaskfla, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request performs a comprehensive update of Babel dependencies across the entire project. The primary goal is to modernize the JavaScript compilation pipeline by upgrading all relevant Babel packages and eliminating plugins that are no longer necessary due to advancements in JavaScript language support or newer Babel preset capabilities. This effort leads to a cleaner and more efficient build configuration.

Highlights

• Babel Dependency Updates: All @babel/* dependencies across the monorepo have been updated to their latest versions, ensuring the project leverages the most recent features and performance improvements from the Babel ecosystem.
• Redundant Plugin Removal: Several Babel proposal plugins, including @babel/plugin-proposal-class-properties, @babel/plugin-proposal-private-methods, and @babel/plugin-proposal-private-property-in-object, have been removed from various configuration files and package.json files. This indicates that these features are now natively supported by the target JavaScript environment or are handled by updated Babel presets, making the explicit plugins redundant.
• Configuration Cleanup: Babel configuration files like babel.config.json and .babelrc.js have been streamlined by removing unnecessary plugin declarations, simplifying the build setup.

Code Review

This pull request effectively updates Babel dependencies and cleans up the configuration by removing redundant plugins. The changes are generally good and align with modern Babel practices. I've identified a couple of areas for improvement: one related to a version mismatch in package.json resolutions, and another concerning a deprecated dependency that can be removed.

[gemini-code-assist]

While updating @babel/types here is correct, the resolutions block in this file (lines 54-58) still pins @babel/types to 7.25.6. This can cause conflicts and prevent this updated version from being used. Please update the resolutions block to 7.29.0 to ensure consistency across the workspace.

[gemini-code-assist]

The @babel/polyfill package is deprecated and should be removed. The root babel.config.json is already configured to use @babel/plugin-transform-runtime with corejs: 3, which handles polyfills automatically without polluting the global scope. This makes the explicit inclusion of @babel/polyfill redundant. Removing this dependency aligns with modern Babel practices and the goal of this PR to remove redundant dependencies.
