🔀 Refactor TestRunner.cs

- Handle invalid choice in Examples.TryGetValue
- Add exit condition for choice "Exit"
- Display a rule before executing example
- Clear console after each iteration

📝 This change refactors the TestRunner.cs file. It handles invalid choices in Examples.TryGetValue, adds an exit condition for the choice "Exit", displays a rule before executing an example, and clears the console after each iteration.
