/**
* Webpack configuration for the Banglar Bhumi Utils Chrome extension.
*
* Produces three separate bundles:
* 1. **Uninjected scripts** – content scripts that run as-is.
* 2. **Injected scripts** – content scripts that are further processed
* so they can be injected into the page DOM.
* 3. **Shared modules** – libraries compiled as standalone files and
* referenced via global variables (`$<hash>`).
*
* Custom loaders and plugins handle dependency ordering, import counting,
* asset-URL rewriting, manifest generation, and declarative-net-rule creation.
