Evaluate new automation tools

[gtrevisan]

automation makes our life easier, so we should rely on all tools that provide a great bang-for-buck ratio.

I'm currently evaluating:

• mypy
• vulture and pytest-vulture
• sourcery
• copilot
• pytest-cov or coverage.py or codecov
• zizmor

any suggestion is appreciated!
