chore: add .gitignore for Node.js and Python artifacts

[RogueTex]

The repository currently lacks a .gitignore file, which means build artifacts, dependencies, and sensitive files are being tracked in version control.

This should include entries for:

Node.js artifacts:

• node_modules/ (dependency directory)
• • dist/ (build output)
• • • .env (environment variables)
• • • • .env.local
        Python artifacts:
• pycache/ (compiled Python bytecode)
• • *.pyc
• • • .Python
• • • • venv/ (virtual environment)
• • • • • env/ (alternative virtual environment directory)
• • • • • • .venv/
            General:
• .DS_Store (macOS)
• • .idea/ (IDE files)
• • • *.log
      Adding a proper .gitignore will:
• Reduce repository size
• • Prevent accidental commits of sensitive data
• • • Improve collaboration experience
• • • • Follow project best practices
