v1.2.0 - Fix product selection, cart pricing, admin tabs + CI/CD

Fix three critical bugs that persisted through v1.1.11-v1.1.14:

- Product selection always empty: meta_query checked _product_type in
  postmeta, but WooCommerce uses the product_type taxonomy. Replaced
  with correct tax_query using NOT IN operator.
- Cart price always 0.00: composable_price_calculated flag persisted
  in session, preventing recalculation on page loads. Removed flag;
  static variable already handles per-request dedup.
- Admin tabs both visible on load: JS now triggers WooCommerce native
  tab click instead of manually toggling panel visibility.

Add Gitea CI/CD release workflow triggered on v* tags.

+## [1.2.0] - 2026-03-01
+
+### Fixed
+
+- **CRITICAL**: Product selection always empty regardless of configuration (categories, tags, or SKUs)
+  - Root cause: Product query used a `meta_query` checking `_product_type` in `wp_postmeta`, but WooCommerce stores product types in the `product_type` **taxonomy** — the `!=` comparison with a non-existent meta key caused an INNER JOIN returning zero results
+  - Fix: Replaced broken `meta_query` with correct `tax_query` using `product_type` taxonomy to exclude composable products
+- **CRITICAL**: Cart price always 0.00 despite correct frontend price calculation
+  - Root cause: `composable_price_calculated` flag was persisted to the cart session, preventing price recalculation on subsequent page loads — but `set_price()` only modifies the in-memory product object and is lost between requests
+  - Fix: Removed per-item session flag; the existing static `$already_calculated` flag already prevents duplicate calculation within a single request
+- **Admin tab rendering**: Both General and Composable Options panels visible on initial page load
+  - Root cause: JavaScript manually showed `#composable_product_data` via `.show()` without hiding the General panel
+  - Fix: Trigger WooCommerce's native tab click instead, so the tab system handles panel visibility correctly
+
+### Added
+
+- **Gitea CI/CD release workflow** (`.gitea/workflows/release.yml`)
+  - Triggered on `v*` tags
+  - Installs PHP 8.3 with production Composer dependencies
+  - Compiles `.po` → `.mo` translations
+  - Verifies plugin version matches tag
+  - Builds release ZIP with proper WordPress directory structure
+  - Generates SHA-256 checksums
+  - Verifies package contains main plugin file and vendor directory
+  - Extracts changelog for release notes
+  - Creates Gitea release with attachments via API
+
+### Removed
+
+- Debug logging from v1.1.14 (no longer needed after root cause identified)
+
+### Technical
+
+- Modified files: includes/Product_Type.php, includes/Cart_Handler.php, assets/js/admin.js
+- New file: .gitea/workflows/release.yml
+- Product query now correctly uses `tax_query` with `product_type` taxonomy (`NOT IN` operator)
+- Cart price recalculated on every request via `woocommerce_before_calculate_totals` hook
+- Admin JS uses `$('ul.product_data_tabs li.composable_options a').trigger('click')` for native WooCommerce tab handling
