Pull request overview

This pull request aims to update the project's packaging configuration and CI infrastructure by modernizing to Python 3.13 and newer Django versions, while removing end-of-life versions. However, the PR introduces several critical issues by referencing non-existent versions of Python (3.14), Django (5.2, 6.0), and GitHub Actions (download-artifact@v7).

Key intended changes:

• Migrate from setup.py/setup.cfg to modern pyproject.toml-only configuration
• Replace multiple linting tools (black, flake8, isort, bandit, pydocstyle) with Ruff
• Modernize CI workflows to use uv instead of pip

The syntax for including another dependency group appears incorrect. The correct syntax for PEP 735 dependency groups should be just the group name as a string reference, not using a dictionary with 'include-group'. This should be changed to reference the test group properly according to the PEP 735 specification.

Suggested change

	{ include-group = "test" },
	"test",
