Initial commit with basic Flask project structure

This commit sets up a minimal Flask project with the following:
- app.py: Contains a simple read_root route.
- requirements.txt: Lists Flask as a dependency.
- .env file: Defines FLASK_APP environment variable for flask run.
- venv/: A virtual environment for project-specific dependencies.
