Tip: `ModuleNotFoundError: No module named 'pkg_resources'` with setuptools >= 82.0.0

Title: ModuleNotFoundError: No module named 'pkg_resources' with setuptools >= 82.0.0

Body:

## Bug

breadability fails to import with setuptools >= 82.0.0, which removed `pkg_resources`.

### Error

File ".../breadability/init.py", line 9, in
import pkg_resources
ModuleNotFoundError: No module named 'pkg_resources'

### Root cause

`__init__.py` uses `pkg_resources` solely for version detection:

```python
import pkg_resources
__version__ = pkg_resources.get_distribution("breadability").version

pkg_resources was deprecated in setuptools 67.5.0 and removed in setuptools 82.0.0
(released February 8, 2026). This breaks any environment with a recent setuptools,
including Python 3.13 on Termux and likely many others.

Fix

Replace with stdlib importlib.metadata (available since Python 3.8):

from importlib.metadata import version
__version__ = version("breadability")

One-line fix. Happy to submit a PR if the maintainer is responsive.
