[PATCH 21/23] tuna: Add pyproject.toml for modern Python packaging

[John Kacur <jkacur@redhat.com>]

Add pyproject.toml to support PEP 517/518 modern Python packaging
while maintaining backwards compatibility with setup.py.

Configuration includes:
- Build system using setuptools>=61.0
- Project metadata (authors, maintainers, version)
- Python version requirement (>=3.10)
- Dependencies (python-linux-procfs)
- Entry points for tuna and oscilloscope commands
- Package classifiers for PyPI
