Initial release — a framework-agnostic PHP SDK for the Whop API, extracted from the Matchable backend.

WhopApiClient facade exposing the full Whop API across 57 resource groups as public readonly properties (PHP namespace Matchable\Whop).
PSR-based transport: a PSR-18 client plus PSR-17 factories (auto-discovered via php-http/discovery), with no framework dependency. All HTTP I/O flows through a single HttpTransport chokepoint.
Typed response DTOs for companies, checkouts, payments, refunds, voids, account links and webhooks; other endpoints return the decoded response array.
A granular exception hierarchy under the WhopException base — WhopApiException (HTTP 4xx/5xx, carries status code and response body), TransportException, SerializationException, MissingArgumentsException, and WebhookVerificationException — so consumers can catch all SDK failures or a specific subtype.
WebhookVerifier for Standard Webhooks signature verification, supporting both whsec_ (production) and ws_ (sandbox) secret formats, with raw-input and PSR-7 request overloads.
Full quality toolchain: PHPStan at level: max, PHP-CS-Fixer, Infection mutation testing, a comprehensive PHPUnit suite, and a GitHub Actions CI workflow.
