Add licensed variable product support for duration-based licenses (v0.5.3)

Customers can now purchase licenses with different durations (monthly, yearly, lifetime) through WooCommerce product variations. Each variation can have its own license validity settings. New features: - LicensedVariableProduct class for variable licensed products - LicensedProductVariation class for individual variations - Per-variation license duration and max activations settings - Duration labels in checkout (Monthly, Quarterly, Yearly, etc.) - Full support for WooCommerce Blocks checkout with variations - Updated translations for German (de_CH) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

 ### 2026-01-26 - Version 0.5.1 - Admin UI Fixes
 **Overview:**
 Bug fix release improving admin UI usability for version management and license overview.
 **Bug Fixes:**
 - Fixed: Product versions in admin now sort by version DESC when adding via AJAX
 - Fixed: License actions in admin overview are now always visible (not just on hover)
 **Modified files:**
 - `assets/css/admin.css` - Added `!important` to `.licenses-table .row-actions` for permanent visibility
 - `assets/js/versions.js` - Added `compareVersions()` function and sorted insertion for AJAX-added versions
 **Technical notes:**
 - Version sorting uses semantic version comparison (major.minor.patch)
 - New versions are inserted in correct sorted position in the table instead of always appending
 - CSS override uses `!important` to overcome WordPress default hover-only behavior for row actions
 - `compareVersions()` function compares version strings numerically (1.10.0 > 1.9.0)

 ### 2026-01-26 - Version 0.5.2 - Per-License Customer Secrets
 **Overview:**
 Security enhancement release adding per-license customer secrets for API response verification. Each customer now receives a unique secret derived from their license key, eliminating the need to share a global server secret.
 **Implemented:**
 - Per-license secret derivation using HKDF-like approach
 - Customer account UI showing API verification secret with collapsible section
 - Copy-to-clipboard functionality for customer secrets
 - Static helper methods in ResponseSigner for secret derivation
 **New methods in ResponseSigner:**
 - `deriveCustomerSecret()` - Static method to derive customer secret from license key and server secret
 - `getCustomerSecretForLicense()` - Static method to get customer secret using configured server secret
 - `isSigningEnabled()` - Static method to check if response signing is configured
 **Modified files:**
 - `src/Api/ResponseSigner.php` - Added static methods for customer secret derivation
 - `src/Frontend/AccountController.php` - Added `signing_enabled` and `customer_secret` to template data
 - `templates/frontend/licenses.html.twig` - Added collapsible secret section with toggle and copy button
 - `assets/css/frontend.css` - Added styles for `.license-row-secret`, `.secret-toggle`, `.secret-content`
 - `assets/js/frontend.js` - Added `toggleSecret()` and `copySecret()` event handlers
 - `docs/server-implementation.md` - Added documentation for per-license secrets
 **Technical notes:**
 - Secret derivation uses HKDF-like approach: `HMAC-SHA256(HMAC-SHA256(license_key, server_secret) + "\x01", server_secret)`
 - Each license gets a unique 64-character hex secret
 - Secrets are only shown when `WC_LICENSE_SERVER_SECRET` is configured
 - Collapsible UI prevents accidental secret exposure
 - If server secret is rotated, all customer secrets change automatically
 **Security improvement:**
 - Customers no longer need access to the master `WC_LICENSE_SERVER_SECRET`
 - If one customer's secret is leaked, other customers are not affected
 - Each license key derives its own unique verification secret
 **Release v0.5.2:**
 - Created release package: `releases/wc-licensed-product-0.5.2.zip` (845 KB)
 - SHA256: `2d61a78ac5ba0f1d115a6401e6dded5b872b18f5530027c371604cbd18e9e27c`

 ### 2026-01-26 - Version 0.5.3 - Variable Licensed Products
 **Overview:**
 Major feature release adding support for WooCommerce variable products. Customers can now purchase licenses with different durations (monthly, yearly, lifetime) as product variations.
 **New files:**
 - `src/Product/LicensedVariableProduct.php` - Variable product class extending `WC_Product_Variable`
 - `src/Product/LicensedProductVariation.php` - Variation class with license settings
 **Implemented:**
 - New `licensed-variable` product type for selling licenses with different durations
 - `LicensedVariableProduct` class extending WooCommerce variable products
 - `LicensedProductVariation` class for individual variation license settings
 - Variation-specific license duration fields in product edit page (days, max activations)
 - Duration labels (Monthly, Quarterly, Yearly, Lifetime) displayed in checkout
 - Variation ID tracking in order domain meta for proper license generation
 - WooCommerce Blocks checkout updated to handle variations with duration labels
 **Modified files:**
 - `src/Product/LicensedProductType.php` - Added licensed-variable type registration, variation hooks
 - `src/License/LicenseManager.php` - Added `isLicensedProduct()` helper, variation support in `generateLicense()`
 - `src/Plugin.php` - Updated license generation to handle variations
 - `src/Checkout/CheckoutController.php` - Variation support in domain field rendering
 - `src/Checkout/CheckoutBlocksIntegration.php` - Variation data in blocks checkout
 - `src/Checkout/StoreApiExtension.php` - Variation ID in Store API schema
 - `assets/js/checkout-blocks.js` - Variation handling in React components and DOM fallback
 **Technical notes:**
 - Variable product type shows in WooCommerce product type selector as "Licensed Variable Product"
 - Each variation can override parent's license duration and max activations
 - Variations are always virtual (licensed products don't ship)
 - `LicensedProductVariation::get_license_duration_label()` returns human-readable duration
 - Order meta `_licensed_product_domains` now includes optional `variation_id` field
 - License generation uses variation settings when `variation_id` is present in order item
 - Backward compatible: existing simple licensed products continue to work unchanged

 ### Per-License Secrets
 Each customer receives a unique secret derived from their license key. This means:
 - Customers only know their own secret, not the master server secret
 - If one customer's secret is leaked, other customers are not affected
 - The server uses HKDF-like derivation to create unique secrets
 #### How Customers Get Their Secret
 Customers can find their per-license verification secret in their account:
 1. Log in to the store
 2. Go to My Account > Licenses
 3. Click "API Verification Secret" under any license
 4. Copy the 64-character hex string
 This secret is automatically derived from the customer's license key and the server's master secret.
 #### Using the Customer Secret
 ```php
 use Magdev\WcLicensedProductClient\SecureLicenseClient;
 use Symfony\Component\HttpClient\HttpClient;
 // Customer uses their per-license secret (from account page)
 $client = new SecureLicenseClient(
    httpClient: HttpClient::create(),
    baseUrl: 'https://shop.example.com',
    serverSecret: 'customer-secret-from-account-page', // 64 hex chars
 );
 $info = $client->validate('XXXX-XXXX-XXXX-XXXX', 'example.com');
 ```
 ### Secret Key Rotation
 To rotate the server secret:
 1. Deploy new secret to server
-2. Update client configurations
+2. All per-license secrets change automatically (they're derived)
-3. Old signatures become invalid immediately
+3. Customers must copy their new secret from their account page
 4. Old signatures become invalid immediately
 For zero-downtime rotation, implement versioned secrets:
