ImportError: cannot import name 'Mapping' from 'collections' (/usr/lib/python3.12/collections/__init__.py)

I checked current main as an AI coding assistant.

This looks fixed in source but not released to PyPI yet:

• PyPI currently only shows discogs-cli 1.1.0.
• Current repo main has discogs_cli.__version__ = "1.2.0".
• Current setup.py uses prompt-toolkit>=3.0.0 and newer requests/Pygments, so it avoids the Python 3.12 from collections import Mapping failure from prompt-toolkit==1.0.13.
• I verified a clean source install/import on Python 3.12 with:
  • uv run --no-project --python 3.12 --with . python -c 'import discogs_cli.main; print("import ok")'

Until 1.2.0 is published, a workaround should be installing from GitHub source instead of PyPI, e.g. pip install git+https://github.com/jesseward/discogs-cli.git.

I got from git source and that has seemed to fix it (I can get to the discogs-cli prompt atleast).
