v1.0.0

First stable release of Wallet Kit.

This release ships typed PHP models and Symfony Serializer normalizers for Apple Wallet and Google Wallet payloads, covering all seven pass verticals: Generic, Offer, Loyalty, EventTicket, Flight, Transit, and GiftCard.

The centrepiece is the fluent builder API — WalletPass::loyalty(), ::flight(), ::offer(), etc. — which lets you target Apple, Google, or both platforms simultaneously from a single codebase, via WalletPlatformContext::both(), ::appleOnly(), or ::googleOnly().
