Pull request overview

Upgrades backend compatibility toward Python 3.12 by removing distutils usage (removed in 3.12) and expanding CI to exercise Python 3.12.

Changes:

• Added a local strtobool helper to replace distutils.util.strtobool().
• Updated call sites to use the new helper instead of distutils.
• Expanded GitHub Actions pytest workflow to run on Python 3.10 and 3.12.

• With a Python-version matrix, the Coveralls upload step will run once per Python version. That typically results in duplicate/competing uploads (or requires Coveralls parallel-build configuration). Consider running Coveralls only for a single matrix entry (e.g., the primary runtime) or configuring per-version flag-name + parallel/parallel-finished so coverage reporting stays accurate.

strtobool() is new code introduced to replace distutils.util.strtobool() for Python 3.12 compatibility, but it currently has no direct unit test coverage. Since kpi/tests/test_utils.py already covers other helpers in kpi.utils.strings (e.g., split_lines_to_list), adding a small test for the accepted true/false strings and the ValueError case would help prevent regressions during the runtime upgrade.

[Copilot]

strtobool() returns 0/1 ints, but Language.featured is a BooleanField. Right now the try branch assigns an int while the except assigns a bool, which mixes types and can leak 0/1 into downstream code. Consider converting to a boolean (e.g., wrap the result in bool(...)) so featured is consistently a bool before constructing the Language object.

Suggested change

	featured = strtobool(row[2])
	featured = bool(strtobool(row[2]))
