Add comprehensive README.md with project information, setup instructions, and usage examples

[Copilot]

Overview

This PR updates the README.md file to provide comprehensive and accurate information about the Test Copilot project, replacing the previous generic template content.

Changes Made

Updated README.md

The README now includes:

• Clear Project Title and Description: Describes this as a Python utility scripts project containing a Hello World script and a number sorting utility
• Accurate Setup Instructions: Replaced incorrect npm-based instructions with proper Python 3 setup steps including cloning, navigating to the project directory, and verifying Python installation
• Comprehensive Usage Examples:
  • Command-line usage for hello.py with expected output
  • Interactive usage example for sort_descending.py with sample input/output
  • Code example demonstrating how to import and use the sort_numbers_descending function programmatically
• Contribution Guidelines: Maintained existing Git workflow instructions with proper bash syntax highlighting

Added .gitignore

Created a comprehensive .gitignore file to exclude Python cache files (__pycache__/), bytecode files, virtual environments, IDE-specific files, and OS-specific files from version control.

Verification

• ✅ All Python scripts tested and confirmed working
• ✅ All usage examples verified to execute correctly
• ✅ CodeQL security scan passed with no issues

The README now provides clear, accurate documentation that matches the actual Python project structure and makes it easy for users to understand, set up, and use the repository.
