restart task button

[egyleader]

it's helpful to have the ability to restart task or part of it again manually :

example scenario :

• i find myself restart tasks manually for multiple reasons (wrong model selected for example and want to start fresh) by copying the task prompt , terminate it , and start new one , but :
  a) this process is boring
  b) it is not really possible in orchestrator mode as terminating the task will result into going back to the parent task automatically and I have to stop both and instruct the orchestrator to start another task , expected : a button to restart the subtask without affecting parent
