     * Installs the plugin into the Eleva instance.

     * Method wrapping behavior:
     * - Stores original `_patchNode` in `renderer._originalPatchNode`
     * - Overrides `renderer._patchNode` to use enhanced attribute handling
     * - Adds `renderer.updateAttributes` and `eleva.updateElementAttributes` helpers
     * - Call `uninstall()` to restore original behavior
     *
     * @param {Eleva} eleva - The Eleva instance to enhance.
     * @param {AttrPluginOptions} options - Plugin configuration options.
     * @param {boolean} [options.enableAria=true] - Enable ARIA attribute handling.
     *        Maps aria-* attributes to DOM properties (e.g., aria-expanded → ariaExpanded).
     * @param {boolean} [options.enableData=true] - Enable data attribute handling.
     *        Syncs data-* attributes with element.dataset for consistent access.
     * @param {boolean} [options.enableBoolean=true] - Enable boolean attribute handling.
     *        Treats empty strings and attribute names as true, "false" string as false.
     * @param {boolean} [options.enableDynamic=true] - Enable dynamic property detection.
     *        Searches element prototype chain for property matches (useful for custom elements).
     * @returns {void}
     * @example
     * // Basic installation with defaults
     * app.use(AttrPlugin);

     * // Custom configuration

     *   enableBoolean: true,
     *   enableDynamic: false  // Disable for performance
