Summary

This PR adds the push method to the Hyperf\Collection\Arr class, following the implementation from Laravel PR #56632.

Changes

• Added push method to Arr class that allows pushing items into arrays using dot notation

• Proper exception handling when target is not an array
• API compatibility with Laravel's implementation

Usage Examples

$array = [];
Arr::push($array, 'office.furniture', 'Desk');
// Result: ['office' => ['furniture' => ['Desk']]]

Arr::push($array, 'office.furniture', 'Chair', 'Lamp');
// Result: ['office' => ['furniture' => ['Desk', 'Chair', 'Lamp']]]

Arr::push($array, null, 'Chris', 'Nuno');
// Result: ['Chris', 'Nuno']
