Ajax Cart for WooCommerce

Ajax Cart for WooCommerce makes buying smoother in two ways:

• On the classic cart page (the [woocommerce_cart] shortcode most stores and classic themes use), totals are recalculated with AJAX as soon as a quantity changes — no “Update cart” click — with -/+ buttons around the quantity.
• A side cart (optional): a cart drawer that slides in from the side when a product is added, with a floating cart button — on classic and block themes alike, on every page but the cart and checkout.

On the newer Cart block (the default for stores created since WooCommerce 8.3), WooCommerce already updates quantities by itself; there the plugin adds a confirmation before an item is removed, and the side cart works the same.

No other hacks, code or theme changes are needed: the features are active as soon as the plugin is.
