Feat: Implement 'cls' Command to Clear Console

[jayambe36]

The command prompt can get cluttered with output. A cls (or clear) command is a standard utility to clear the console screen, providing a cleaner workspace for the user.

This can be implemented in Java by printing a sequence of new lines or by using a more advanced method to clear the console, which this solution does for better compatibility
