Fix template quirks and bump version to 0.1.0

Audit and fix 14 Twig templates for escaping bugs, CSS conflicts,
and missing Bootstrap styling:
- Fix nl2br/esc_html filter order in order details
- Add WC gallery modifier classes for zoom/photoswipe JS init
- Fix HTML entity double-encoding in headings (up-sells, cross-sells, related)
- Remove wrong 'is defined' guards on function calls
- Remove duplicate deprecated hooks in dashboard
- Add |raw to brand description HTML filter chain
- Add role="alert" for accessibility, |esc_attr on notification types
- Style mini-cart remove button as Bootstrap btn
- Make shipping form-check class conditional
- Add shop_table CSS reset and gallery opacity fallback

+
+**Scope:** Created Bootstrap 5 two-column layout for single product pages. Then audited all ~90 Twig templates for WooCommerce CSS quirks, Twig escaping bugs, and missing Bootstrap styling.
+
+**Single product layout (3 files):**
+
+- `woocommerce/content-single-product.php` — Bridge file for `wc_get_template_part()` interception
+- `templates/content-single-product.html.twig` — Two-column `row gx-4 gx-lg-5` grid (images left, summary right)
+- `assets/css/wc-bootstrap.css` — Float/width reset, sale badge positioning, shop_table border reset, gallery opacity fallback
+
+**Template quirks audit (14 files fixed):**
+
+- `order/order-details.html.twig` — Fixed `|nl2br|esc_html` filter order (was escaping `<br>` tags)
+- `single-product/product-image.html.twig` — Added WC gallery modifier classes + opacity:0 for JS init
+- `brands/brand-description.html.twig` — Added `|raw` to HTML-producing filter chain
+- `single-product/up-sells.html.twig`, `cart/cross-sells.html.twig`, `single-product/related.html.twig` — Fixed `&hellip;` double-encoding in headings
+- `myaccount/dashboard.html.twig` — Removed duplicate deprecated hook fires
+- `product-searchform.html.twig` — Replaced `&hellip;` entity with Unicode `…`
+- `cart/cart-totals.html.twig`, `checkout/review-order.html.twig`, `checkout/form-login.html.twig`, `checkout/terms.html.twig` — Removed wrong `function() is defined` guards
+- `wc-base.html.twig` — Added `|esc_attr` on notification type in class attribute
+- `global/form-login.html.twig` — Added `is defined` guard on `hidden` variable
+- `single-product/add-to-cart/variation.html.twig` — Added `role="alert"` for accessibility
+- `cart/mini-cart.html.twig` — Changed remove link to Bootstrap `btn btn-sm btn-outline-danger`
+- `cart/cart-shipping.html.twig` — Made `form-check` class conditional on multiple shipping methods
