v1.0.0 — Initial release

First release of the SparkCRM DTC Checkout PHP SDK.

Highlights

• Full funnel: init() → createLead() → createOrder() (auto-routes lead vs full order) → processUpsell() → completeOrder()
• PayPal redirect + capture flow, with cancel detection (wasCanceled() / abandon())
• Decline salvage: reprocessPayment() / reprocessUpsell(), with retry-cap results (isCapped())
• Tax quotes, refunds, subscription status, order/transaction search
• Pluggable state stores: Session (default), PSR-16 Cache, Signed Cookie, Array, Layered
• Tracking auto-capture + param normalization, proxy-aware client IP, card-expiry normalization
• Typed exceptions, retry/backoff, test mode + test-card helpers
• Optional Laravel bridge (service provider + Spark facade)
