Pull Request Overview

This PR refactors the pylint check implementation to use a centralized virtual environment command execution pattern. The changes improve code maintainability by eliminating duplicate pip freeze logic and standardizing how commands are run within virtual environments.

Key changes:

• Extracted pip freeze logic into a reusable pip_freeze() method in the base Check class
• Replaced direct check_call() usage with the run_venv_command() method for better error handling
• Added improved stdout/stderr output handling for both successful and failed pylint runs

The TODO comment 'why???' is unclear and doesn't explain what needs to be addressed. Either remove this comment if the code is correct, or clarify what question needs to be resolved (e.g., '# TODO: Determine if stdout/stderr printing is necessary or if logging would be more appropriate').

Suggested change

	# todo: why???
	# TODO: Determine if printing stdout/stderr is necessary or if logging would be more appropriate.

[nitpick] Using os.getcwd() as the current working directory is redundant since that's the default behavior of subprocess.run(). Consider removing the cwd parameter or using a more specific directory if needed for clarity.

Suggested change

	result = subprocess.run(command, cwd=os.getcwd(), check=True, capture_output=True, text=True)
	result = subprocess.run(command, check=True, capture_output=True, text=True)
