feat: Verifier accept Symfony HttpFoundation Request

[EstimationApp]

Please describe your feature request.

Symfony is one of the most widely used PHP frameworks, and its controllers receive a Symfony\Component\HttpFoundation\Request, not a PSR-7 RequestInterface.

Today, Symfony users integrating Paddle webhooks must:

1. Pull in symfony/psr-http-message-bridge.
2. Pull in a PSR-7 implementation such as nyholm/psr7.
3. Wire up an HttpMessageFactoryInterface service.
4. Convert the incoming request on every webhook call before handing it to the verifier.

This is a non-trivial amount of boilerplate for what should be a one-liner.

Describe your solution.

Given Symfony's popularity in the PHP ecosystem, accepting its native Request object directly would significantly lower the barrier to integration and improve developer experience.

(new Verifier())->verify(
    Symfony\Component\HttpFoundation\Request|Psr\Http\Message\RequestInterface $request,
    new Secret('WEBHOOK_SECRET_KEY')
);

Describe alternatives you have considered.

Hey @EstimationApp 👋 .. thanks for reaching out with feedback here.

Our goal is to keep the core Paddle PHP SDK framework-agnostic to ensure it remains stable, PSR-compliant, and usable in any PHP environment without the risk of version-lock.

That said, we definitely hear the need for a better "plug-and-play" experience. We're planning to explore dedicated bridge packages (for Laravel, Symfony, etc.) that will depend on this core SDK. This allows the base to stay lean while providing the native, drop-in support you're looking for.
