/**
 * "use client" detector loader.
 *
 * Attached by RSCRspackPlugin to every JS/TS module during compilation.
 * Reads the source, checks if the file starts with a `"use client"`
 * directive (accounting for BOM, shebangs, and leading comments), and if
 * so adds the module's resourcePath to a per-compilation Set keyed by the
 * `CLIENT_MODULES_KEY` Symbol. The plugin consumes that Set at
 * `processAssets` time to emit the manifest.
 *
 * The loader passes the source through unchanged — it is purely a reporter.
 *
 * IMPORTANT: communication with the plugin goes via a Symbol-keyed
 * property on the compilation object (`compilation[CLIENT_MODULES_KEY]`).
 * The plugin eagerly creates the Set in `thisCompilation` so the loader
 * never races on initialization.
