Switon's invocation hook contracts for method-level guards and interceptors.

This package defines the attributes and hook contracts; [Invoker](../invoker/README.md) executes them at runtime.

Highlights
----------

[](#highlights)

- **Attribute-based hooks:** guards and interceptors attach behavior directly to methods.
- **Pre-execution checks:** guarded methods can be examined before they run.
- **Around-call wrapping:** interceptors can run before, after, or on exception.
- **Reusable base hook:** `Interceptor` covers the common partial-lifecycle case.
- **Reusable invocation path:** other components can share the same call flow.

Installation
------------

[](#installation)

```
composer require switon/invocation
```

Quick Start
-----------

[](#quick-start)

```
use Attribute;
use ReflectionMethod;
use Switon\Invocation\Attribute\GuardInterface;
use Switon\Http\Exception\ForbiddenException;
use Switon\Http\RequestInterface;

#[Attribute(Attribute::TARGET_METHOD)]
final class IpGuard implements GuardInterface
{
    public function __construct(
        private array $ips,
    ) {
    }

    public function handle(RequestInterface $request, ReflectionMethod $method): void
    {
        if (!in_array($request->ip(), $this->ips, true)) {
            throw ForbiddenException::of('Access denied.');
        }
    }
}

final class AccountService
{
    #[IpGuard(['127.0.0.1'])]
    public function deleteAction(int $id): void
    {
    }
}
```
