fix: align formatting checks

[krowvin]

Summary

• pin Black to 24.10.0 for all supported local and CI environments
• run pre-commit through Poetry in Code Check so CI uses the locked formatter versions
• document the local all-files quality command and its expected rewrite behavior
• apply the resulting Black 24 formatting drift on current main

Validation

• poetry install --with dev --no-interaction
• poetry run black --version
• poetry run pre-commit run --all-files --show-diff-on-failure
• poetry run pytest -q
• poetry check

Note: local validation ran with Python 3.14.3. CI uses Python 3.12 and should report Black 24.10.0 in the Code Check log.
