steam-backlog-enforcer/steam_backlog_enforcer/tests/test_scanning.py
Krzysztof kuhy Rudnicki 551b8a4f95 chore: set up as standalone repo
Extracted from testsAndMisc monorepo. Changes:
- Rewrote imports from python_pkg.steam_backlog_enforcer.* → steam_backlog_enforcer.*
- Moved run.sh, install.sh, README.md, service file to repo root
- Added standalone pyproject.toml, requirements.txt, .pre-commit-config.yaml, .gitignore
- Added GitHub Actions CI workflows (tests + pre-commit)
