Webpack Duplicate Package Checker Plugin

The `duplicate-package-checker-webpack-plugin` is a Webpack plugin designed to identify and warn developers when their JavaScript bundle contains multiple, redundant versions of the same npm package. This situation often arises in complex projects due to transitive dependencies, leading to unnecessary bundle bloat and potential runtime conflicts or bugs. The plugin operates during the Webpack build process, flagging these duplicates to help maintain optimal bundle size and application stability. The current stable version is `3.0.0`. While it remains a popular tool with significant weekly downloads, its maintenance status is classified as inactive, with no new versions released to npm in the past 12 months, indicating a slow or potentially discontinued release cadence. Its key differentiator is providing clear, actionable warnings and offering explicit resolution strategies like `webpack.resolve.alias` to mitigate the issues caused by duplicate packages.
