Pass the whole native payload to a lone array #[On] parameter

[ngunyimacharia]

Problem

A native event listener like this crashes with BindingResolutionException:

#[On('chat-stream:delta')]
public function onDelta(array $payload): void

Named binding looks for a payload key called payload. It finds none, and the container can't resolve a bare array.

Fix

When a listener has exactly one array parameter and the payload has no key with that name, the listener gets the whole payload.

A matching key still binds by name as before. So onItems(array $items) with ['items' => [...]] still gets just $items.

Tests

tests/Feature/Edge/NativeEventPayloadBindingTest.php covers both cases.

This works on its own and also merges cleanly with #505. Together they let nested components use this listener shape.

Superseded by #510, which does this explicitly through a typed NativeEventPayload parameter instead of guessing from a missing key name.
