Whop Symfony Bundle Laravel Package

Added

• Initial pre-stable release.
• Autowired WhopApiClient and WebhookVerifier from the Whop PHP SDK — consumers reach them via type-hint with no extra configuration.
• Compile-time-validated whop: configuration tree (api_key, webhook_secret, base_url, http_client, webhook_path).
• Bundle-owned WhopWebhookController mounted at the configurable webhook_path (default /_whop/webhook), returning 204 / 401 / 400 per the Standard Webhooks contract.
• WhopWebhookReceivedEvent for zero-config consumer subscription via #[AsEventListener].
• Three documented handler-override paths: implement WhopWebhookHandlerInterface, extend EventDispatchingWebhookHandler, or decorate the default handler with #[AsDecorator].
• Flex recipe targeting symfony/recipes-contrib — registers the bundle, drops config/packages/whop.yaml + config/routes/whop.yaml, and appends the required env vars to .env.
