/**
 * This class is used to create a dynamic synced config for plugins.
 *
 * [!IMPORTANT!]
 * The methods are **sync** in the main process and **async** in the renderer process.
 *
 * @param {string} name - The name of the plugin.
 * @param {boolean} [options.enableFront] - Whether the config should be available in front.js. Default: false.
 * @param {object} [options.initialOptions] - The initial options for the plugin. Default: loaded from store.
 *
 * @example
 * const { PluginConfig } = require("../../config/dynamic");
 * const config = new PluginConfig("plugin-name", { enableFront: true });
 * module.exports = { ...config };
 * 
 * // or
 * 
 * module.exports = (win, options) => {
 *  const config = new PluginConfig("plugin-name", {
 *  	enableFront: true,
 *  	initialOptions: options,
 *  });
 *  setupMyPlugin(win, config);
