refactor: Convert Games Python CLI scripts to follow procedural guidelines

[mrdeyroy]

Description

This pull request addresses Issue #805 by refactoring all purely CLI-based projects within the games/ directory to adhere strictly to the project's procedural programming guidelines (No def, No class).

Fixes #805

Changes Made:

• Completely refactored 12 CLI game scripts from Object-Oriented/Functional paradigms into pure procedural while True: game loops.
• Replaced complex OOP mechanisms (like AI paths, card tracking, and timed threads) with flat control flow logic using dictionaries and lists for state management.
• Ensured all visual elements, console clearing, CLI styling, emojis, and gameplay features remain intact exactly as they were before the refactor.
• Rewrote the unit test module test_number_guessing.py to properly execute and test procedural scripts utilizing exec() combined with unittest.mock.patch.

Testing:

• Conducted manual edge-case testing for non-blocking I/O elements (e.g., in Whack-a-Mole) to ensure cross-platform compatibility within the procedural constraint.
