Handled Concurrency run() fails when passing an array instead of a cl…

[shaikhanaas9820]

The original run method only works for closures because it uses SerializableClosure.

To handle both closures and arrays, you need to:

Check the type of each task.

Serialize closures using SerializableClosure.

Serialize arrays or other data using json_encode.

Update the subprocess command to handle both serialized closures and JSON-encoded data.
