New pipeline() entity orm method

[techmahedy]

The method allows developers to apply a series of collection transformations to query results using a clean, composable pipeline pattern.

Example: Processing Completed Orders

$processed = Order::query()
    ->where('status', 'completed')
    ->pipeline([
        fn ($col) => $col->filter(fn ($o) => $o->total > 100),
        fn ($col) => $col->take(10),
    ]);
