CoreJS Upgrade Webpack Plugin

A webpack plugin that transforms core-js v2 require/module paths to core-js v3 counterparts during bundling. Current stable version is 4.0.1 with maintenance-level releases. It resolves mismatched core-js versions by mapping old path patterns to new ones, preventing bundle bloat and runtime errors from library dependencies. Supports custom resolve directories via resolveFrom option. Released intermittently; uses core-js's path mapping to ensure the latest core-js is used everywhere. Differentiator: automates migration in existing webpack setups without manual code changes.
