[Bug]: Using `--mutate --parallel --processes=X` ignores num processes

[rabrowne85]

What Happened

When you run Pest 3 with the following options:

./vendor/bin/pest --mutate --parallel --processes=x

it should limit the processes to the value specified. However, it ignores the option entirely.

How to Reproduce

Running the above command.

Sample Repository

No response

Pest Version

3.0.1

PHP Version

8.3.10

Operation System

macOS

Notes

Looking at the source for the plugin, the ProcessesOption@match() function seems to be a bit greedy. Locally adjusting the function to the following seems to resolve the issue:

    public static function match(string $argument): bool
    {
        return $argument === str_starts_with($argument, sprintf('--%s=', self::ARGUMENT));
    }
