`pkg_resources `import fails on Python 3.12 due to missing `setuptools `dependency

[kt-devoss]

Hi, thanks for maintaining this project --- I encountered an issue with Python 3.12.

Summary

git-ai-commit fails to run on Python 3.12 with ModuleNotFoundError: No module named 'pkg_resources'.

Steps to Reproduce

1. Install Python 3.12 (clean venv)
2. pip install git-ai-commit
3. Run git-ai-commit --help

Actual Result

    ...
ModuleNotFoundError: No module named 'pkg_resources'

Root Cause

ai_commit_msg/utils/utils.py imports pkg_resources, which is part of setuptools,
but setuptools is not listed in install_requires in setup.cfg.

Expected Behavior

Installation should include all required dependencies.

Suggested Fix

Short-term (to fix runtime error):

Add setuptools>=65.0 to install_requires in setup.cfg, e.g.:

[options]
install_requires =
    setuptools>=65.0
    click>=8.0
    ...

Long-term (to address deprecation):

Replace pkg_resources with the standard library alternative importlib.metadata,
since pkg_resources is deprecated and scheduled for removal after 2025-11-30.

Environment

python -V
Python 3.12.10

pip show git-ai-commit
