Wrap the closure return type in withFreshQueryLog()

[SanderMuller]

withFreshQueryLog() is annotated:

@param  (\Closure(): array{query: string, bindings: array, time: float|null}[])  $callback

No phpdoc standard settles whether that trailing [] belongs to the return type or to the whole closure. PHPStan binds it to the return type, so $callback is a closure returning a list of log entries. Mago, another static analyser, binds it to the closure and reads $callback as an array of closures. That contradicts the method's own @return array{...}[] and the body doing $result = $callback().

Wrapping the return type in parentheses says which one was meant, and both analysers then agree. PHPStan's inference does not change. I ran both forms and each gives:

Closure(): array<array{query: string, bindings: array, time: float|null}>

Mago's maintainer suggested this form for the same reason, since neither analyser can change its precedence without breaking its own users: carthage-software/mago#2310

This is the only annotation of this shape in the framework.
