build(deps-dev): bump ruff from 0.15.20 to 0.16.4. Closes #60

[opbot-xd]

Description

This PR bumps the development dependency ruff from version 0.15.20 to 0.16.4, updates .github/.pre-commit-config.yaml to v0.16.4, and adds CPY001 (flake8-copyright) to the ignored lint rules in pyproject.toml.

Because select = ["ALL"] is enabled for Ruff, upgrading to 0.16.4 triggered CPY001 (missing copyright header) on all 13 Python source and test files. Since this project uses a repository-level MIT license without per-file copyright headers, CPY001 is ignored.

Hi @regulartim, I hope its fine to add exception for this rule, or should we add notice at top of all files like we have in some files of Greedybear?

[opbot-xd]

I checked if we add this line at the very first line of each file (before module docstrings or imports):

# Copyright (c) 2021 The Honeynet Project

We were able to address this rule. Total 13 files required it.

Hey @opbot-xd ! For me it's fine to add an exception for this rule.
