CRITICAL: Key derivation now uses native hash_hkdf() for RFC 5869
compliance. Previous custom implementation was incompatible with
the magdev/wc-licensed-product-client library.
Changes:
- ResponseSigner::deriveCustomerSecret() now uses hash_hkdf()
- Added missing domain validation to /activate endpoint
- Customer secrets will change after upgrade (breaking change)
The signature algorithm now matches the client's ResponseSignature::deriveKey():
- IKM: server_secret
- Length: 32 bytes
- Info: license_key

Fixed HTTP status codes for API responses:
- /validate now returns 404 for license_not_found (was 403)
- Added status code mapping: 404 not found, 500 server errors, 403 others
Added configurable rate limiting:
- WC_LICENSE_RATE_LIMIT constant for requests per window
- WC_LICENSE_RATE_WINDOW constant for window duration in seconds
Fixed license_key validation:
- Now enforces minimum 8 characters across all endpoints
