Problem
When a user presses Ctrl-C twice in a row, the application currently prints two different interrupt messages:
run_interactive_session()main()This creates a confusing user experience with duplicate messages.
Solution
This PR implements a clean fix using an interrupt tracking flag:
_interrupt_handledflag to theCLIAppclass to track whether aKeyboardInterrupthas already been handledrun_interactive_session()to set the flag when it handles aKeyboardInterruptmain()to check the flag before printing its own interrupt messageResult
Now only one clean interrupt message is displayed, regardless of how many times Ctrl-C is pressed. The fix maintains existing behavior while eliminating the duplicate message issue.
