Enhance the exit mechanism of the pluto cli

[jianzs]

Describe the feature

Currently, the pluto cli command is designed to require two presses of Ctrl-C to exit, as a measure to prevent accidental exits. However, the intended functionality is to pass the SIGINT signal to the simulator in order to initiate a graceful cleanup of resources. The first press of Ctrl-C is meant to be ignored by the cli and subsequently passed to the simulator. Upon receiving the signal, the simulator should perform a graceful cleanup. The second press of Ctrl-C should then be caught by the cli to exit the command line interface.

So, the current behavior is such that after the first press of Ctrl-C, the simulator exits. This is not the intuitive behavior that we expect.

What we expect are two possible behaviors:

• Upon pressing Ctrl-C once, the simulator and cli should gracefully exit.
• Alternatively, two presses of Ctrl-C should be required for the simulator to exit, ensuring that the application remains operational after the first press.
