Webpack Pre-Build Hook Plugin

The `pre-build-webpack` package provides a Webpack plugin that allows developers to execute a custom callback function immediately before the Webpack build process commences. Currently at version 0.1.0, the package appears to be an early-stage project that has seen no updates in several years, suggesting it is no longer actively maintained. Its core functionality is to offer a simple hook for pre-build tasks, such as cleaning directories, preparing environment variables, or dynamically adjusting configuration, prior to any asset compilation. This differentiates it from post-build plugins like `on-build-webpack` by targeting an earlier stage in the compilation lifecycle. Given its age and low version number, users should be cautious about its compatibility with modern Webpack versions (v4, v5, or v6+) and the availability of similar or native functionality within Webpack itself.
