Implement Rock-Paper-Scissors Console Application

[Copilot]

This PR implements a Python-based Rock-Paper-Scissors console game as requested in the issue. The game follows a "best out of 3" format, where the first player to reach 3 points wins.

Implementation Details

• Created a new Python file in personas/app-dev/games/rock_paper_scissors.py
• Implemented functions for:
  • User input collection with validation
  • Random computer selection
  • Game logic to determine the winner of each round
  • Scoring system to track points
  • Game loop that continues until someone reaches 3 points

Features

• Clean, modular code with appropriate function separation
• Clear console interface with score tracking
• Input validation to ensure users enter valid choices
• Proper error handling for keyboard interrupts
• Well-documented code with docstrings explaining functionality

Code Quality

• Code passes pylint with a 10/10 score
• Updated .gitignore to exclude Python cache files (__pycache__/, *.pyc, etc.)
• Used modern Python features like f-strings for readable string formatting

Usage

The game can be played by running:

python3 personas/app-dev/games/rock_paper_scissors.py

Fixes #1.
