/**
 * Hooks and events registry
 *
 * @remarks
 * Supports async and sync value hooks as well as asyncronous events.
 *
 * @example
 * Add a new entry to the `webpack.externals` configuration:
 *
 * ```ts
 * hooks.on(
 *   'build.externals',
 *   externals => ({
 *     ...externals,
 *     $: 'jquery',
 *   }),
 * )
 * ```
 *
 * @example
 * Change the `webpack.output.filename` format:
 *
 * ```ts
 * hooks.on(
 *   'build.output.filename',
 *   () => '[name].[hash:4]',
 * )
 * ```
 *
 * @example
 * Filter a value through any registered hooks:
 *
 * ```ts
 * hooks.filter('build.output.filename', DEFAULT_VALUE)
 * ```
 *
 * @example
 * Filter an async value through any registered hooks:
 *
 * ```ts
 * await hooks.filterAsync('my-event-name', async () => DEFAULT_VALUE)
 * ```
