Add setup.py with requirements parsing for packaging

[abdelkadermeflahi6-web]

Motivation

• Provide setuptools packaging and automatic dependency loading from requirements.txt so the project can be installed and distributed.

Description

• Add setup.py that uses find_packages(), sets name="greenflow" and version="0.1.0", and implements parse_requirements() to populate install_requires from requirements.txt while ignoring blank and comment lines.

Testing

• Ran python -m py_compile setup.py which completed successfully.
