Pull request overview

This PR updates the repository’s wording and identifiers to prefer “Rspack” over “webpack”, aligning documentation/comments and a few internal parameter names with the @rspack/plugin-react-refresh branding.

Changes:

• Updated a splitChunks cacheGroup test regex used by the test harness.
• Renamed some runtime parameter names (e.g., webpackHot → hot) and adjusted related comments/JSDoc.
• Removed a webpack-specific explanatory comment in the plugin entrypoint.

• The JSDoc now describes moduleId/exports as coming from “Rspack module” objects, but this file still relies on the webpack-compatible runtime API (/* global __webpack_require__ */ and __webpack_require__.c[moduleId]). Consider updating the wording to reflect that these are webpack-compatible module IDs/exports (as implemented by Rspack), to avoid confusing readers and consumers.

/**
 * Extracts exports from a Rspack module object.
 * @param {string} moduleId An Rspack module ID.
 * @returns {*} An exports object from the module.
 */
function getModuleExports(moduleId) {
  if (typeof moduleId === 'undefined') {
    // `moduleId` is unavailable, which indicates that this module is not in the cache,
    // which means we won't be able to capture any exports,
    // and thus they cannot be refreshed safely.
    // These are likely runtime or dynamically generated modules.
    return {};
  }

  var maybeModule = __webpack_require__.c[moduleId];
  if (typeof maybeModule === 'undefined') {
